CROSS-REFERENCE TO RELATED APPLICATIONS
BACKGROUND
[0002] Wireless devices communicate with base stations and the power of transmissions between
those devices can be determined in a variety of ways.
SUMMARY
[0003] The following summary presents a simplified summary of certain features. The summary
is not an extensive overview and is not intended to identify key or critical elements.
[0004] Wireless communications may comprise transmission/reception between a wireless device
and one or more base stations via one or more cells in a communication network. For
example, an uplink transmission, from a wireless device, may be sent to a base station
via a serving cell and/or via a non-serving cell. A transmission power for the uplink
transmission may be determined based on one or more default power control parameters.
One or more default power control parameters used for transmission via a serving cell
may be different from one or more default power control parameters used for transmission
via a non-serving cell, for example, based on one or more differences between the
serving cell and the non-serving cell, such as locations of the wireless device relative
to the serving cell and non-serving cell, channel conditions for transmissions via
the serving cell and non-serving cell, and/or the like. A default power control parameter
may be determined based on a resource via which a downlink transmission is received
from a base station and/or based on an indication sent by the base station. Using
different default power control parameters for a serving cell and a non-serving cell
may provide advantages such as improved transmission power control, reduced interference,
reduced error rates, and/or improved data rates.
[0005] These and other features and advantages are described in greater detail below.

DETAILED DESCRIPTION
[0007] The accompanying drawings and descriptions provide examples. It is to be understood
that the examples shown in the drawings and/or described are non-exclusive, and that
features shown and described may be practiced in other examples. Examples are provided
for operation of wireless communication systems, which may be used in the technical
field of multicarrier communication systems. More particularly, the technology disclosed
herein may relate to transmission power determination for wireless communication.
[0008] FIG. 1A shows an example communication network 100. The communication network 100
may comprise a mobile communication network). The communication network 100 may comprise,
for example, a public land mobile network (PLMN) operated/managed/run by a network
operator. The communication network 100 may comprise one or more of a core network
(CN) 102, a radio access network (RAN) 104, and/or a wireless device 106. The communication
network 100 may comprise, and/or a device within the communication network 100 may
communicate with (e.g., via CN 102), one or more data networks (DN(s)) 108. The wireless
device 106 may communicate with one or more DNs 108, such as public DNs (e.g., the
Internet), private DNs, and/or intra-operator DNs. The wireless device 106 may communicate
with the one or more DNs 108 via the RAN 104 and/or via the CN 102. The CN 102 may
provide/configure the wireless device 106 with one or more interfaces to the one or
more DNs 108. As part of the interface functionality, the CN 102 may set up end-to-end
connections between the wireless device 106 and the one or more DNs 108, authenticate
the wireless device 106, provide/configure charging functionality, etc.
[0009] The wireless device 106 may communicate with the RAN 104 via radio communications
over an air interface. The RAN 104 may communicate with the CN 102 via various communications
(e.g., wired communications and/or wireless communications). The wireless device 106
may establish a connection with the CN 102 via the RAN 104. The RAN 104 may provide/configure
scheduling, radio resource management, and/or retransmission protocols, for example,
as part of the radio communications. The communication direction from the RAN 104
to the wireless device 106 over/via the air interface may be referred to as the downlink
and/or downlink communication direction. The communication direction from the wireless
device 106 to the RAN 104 over/via the air interface may be referred to as the uplink
and/or uplink communication direction. Downlink transmissions may be separated and/or
distinguished from uplink transmissions, for example, based on at least one of: frequency
division duplexing (FDD), time-division duplexing (TDD), any other duplexing schemes,
and/or one or more combinations thereof.
[0010] As used throughout, the term "wireless device" may comprise one or more of: a mobile
device, a fixed (e.g., nonmobile) device for which wireless communication is configured
or usable, a computing device, a node, a device capable of wirelessly communicating,
or any other device capable of sending and/or receiving signals. As non-limiting examples,
a wireless device may comprise, for example: a telephone, a cellular phone, a Wi-Fi
phone, a smartphone, a tablet, a computer, a laptop, a sensor, a meter, a wearable
device, an Internet of Things (IoT) device, a hotspot, a cellular repeater, a vehicle
road side unit (RSU), a relay node, an automobile, a wireless user device (e.g., user
equipment (UE), a user terminal (UT), etc.), an access terminal (AT), a mobile station,
a handset, a wireless transmit and receive unit (WTRU), a wireless communication device,
and/or any combination thereof.
[0011] The RAN 104 may comprise one or more base stations (not shown). As used throughout,
the term "base station" may comprise one or more of: a base station, a node, a Node
B (NB), an evolved NodeB (eNB), a gNB, an ng-eNB, a relay node (e.g., an integrated
access and backhaul (IAB) node), a donor node (e.g., a donor eNB, a donor gNB, etc.),
an access point (e.g., a Wi-Fi access point), a transmission and reception point (TRP),
a computing device, a device capable of wirelessly communicating, or any other device
capable of sending and/or receiving signals. A base station may comprise one or more
of each element listed above. For example, a base station may comprise one or more
TRPs. As other non-limiting examples, a base station may comprise for example, one
or more of: a Node B (e.g., associated with Universal Mobile Telecommunications System
(UMTS) and/or third-generation (3G) standards), an Evolved Node B (eNB) (e.g., associated
with Evolved-Universal Terrestrial Radio Access (E-UTRA) and/or fourth-generation
(4G) standards), a remote radio head (RRH), a baseband processing unit coupled to
one or more remote radio heads (RRHs), a repeater node or relay node used to extend
the coverage area of a donor node, a Next Generation Evolved Node B (ng-eNB), a Generation
Node B (gNB) (e.g., associated with NR and/or fifth-generation (5G) standards), an
access point (AP) (e.g., associated with, for example, Wi-Fi or any other suitable
wireless communication standard), any other generation base station, and/or any combination
thereof. A base station may comprise one or more devices, such as at least one base
station central device (e.g., a gNB Central Unit (gNB-CU)) and at least one base station
distributed device (e.g., a gNB Distributed Unit (gNB-DU)).
[0012] A base station (e.g., in the RAN 104) may comprise one or more sets of antennas for
communicating with the wireless device 106 wirelessly (e.g., via an over the air interface).
One or more base stations may comprise sets (e.g., three sets or any other quantity
of sets) of antennas to respectively control multiple cells or sectors (e.g., three
cells, three sectors, any other quantity of cells, or any other quantity of sectors).
The size of a cell may be determined by a range at which a receiver (e.g., a base
station receiver) may successfully receive transmissions from a transmitter (e.g.,
a wireless device transmitter) operating in the cell. One or more cells of base stations
(e.g., by alone or in combination with other cells) may provide/configure a radio
coverage to the wireless device 106 over a wide geographic area to support wireless
device mobility. A base station comprising three sectors (e.g., or n-sector, where
n refers to any quantity n) may be referred to as a three-sector site (e.g., or an
n-sector site) or a three-sector base station (e.g., an n-sector base station).
[0013] One or more base stations (e.g., in the RAN 104) may be implemented as a sectored
site with more or less than three sectors. One or more base stations of the RAN 104
may be implemented as an access point, as a baseband processing device/unit coupled
to several RRHs, and/or as a repeater or relay node used to extend the coverage area
of a node (e.g., a donor node). A baseband processing device/unit coupled to RRHs
may be part of a centralized or cloud RAN architecture, for example, where the baseband
processing device/unit may be centralized in a pool of baseband processing devices/units
or virtualized. A repeater node may amplify and send (e.g., transmit, retransmit,
rebroadcast, etc.) a radio signal received from a donor node. A relay node may perform
the substantially the same/similar functions as a repeater node. The relay node may
decode the radio signal received from the donor node, for example, to remove noise
before amplifying and sending the radio signal.
[0014] The RAN 104 may be deployed as a homogenous network of base stations (e.g., macrocell
base stations) that have similar antenna patterns and/or similar high-level transmit
powers. The RAN 104 may be deployed as a heterogeneous network of base stations (e.g.,
different base stations that have different antenna patterns). In heterogeneous networks,
small cell base stations may be used to provide/configure small coverage areas, for
example, coverage areas that overlap with comparatively larger coverage areas provided/configured
by other base stations (e.g., macrocell base stations). The small coverage areas may
be provided/configured in areas with high data traffic (or so-called "hotspots") or
in areas with a weak macrocell coverage. Examples of small cell base stations may
comprise, in order of decreasing coverage area, microcell base stations, picocell
base stations, and femtocell base stations or home base stations.
[0015] Examples described herein may be used in a variety of types of communications. For
example, communications may be in accordance with the Third-Generation Partnership
Project (3GPP) (e.g., one or more network elements similar to those of the communication
network 100), communications in accordance with Institute of Electrical and Electronics
Engineers (IEEE), communications in accordance with International Telecommunication
Union (ITU), communications in accordance with International Organization for Standardization
(ISO), etc. The 3GPP has produced specifications for multiple generations of mobile
networks: a 3G network known as UMTS, a 4G network known as Long-Term Evolution (LTE)
and LTE Advanced (LTE-A), and a 5G network known as 5G System (5GS) and NR system.
3GPP may produce specifications for additional generations of communication networks
(e.g., 6G and/or any other generation of communication network). Examples may be described
with reference to one or more elements (e.g., the RAN) of a 3GPP 5G network, referred
to as a next-generation RAN (NG-RAN), or any other communication network, such as
a 3GPP network and/or a non-3GPP network. Examples described herein may be applicable
to other communication networks, such as 3G and/or 4G networks, and communication
networks that may not yet be finalized/specified (e.g., a 3GPP 6G network), satellite
communication networks, and/or any other communication network. NG-RAN implements
and updates 5G radio access technology referred to as NR and may be provisioned to
implement 4G radio access technology and/or other radio access technologies, such
as other 3GPP and/or non-3GPP radio access technologies.
[0016] FIG. 1B shows an example communication network 150. The communication network may
comprise a mobile communication network. The communication network 150 may comprise,
for example, a PLMN operated/managed/run by a network operator. The communication
network 150 may comprise one or more of: a CN 152 (e.g., a 5G core network (5G-CN)),
a RAN 154 (e.g., an NG-RAN), and/or wireless devices 156A and 156B (collectively wireless
device(s) 156). The communication network 150 may comprise, and/or a device within
the communication network 150 may communicate with (e.g., via CN 152), one or more
data networks (DN(s)) 170. These components may be implemented and operate in substantially
the same or similar manner as corresponding components described with respect to FIG.
1A.
[0017] The CN 152 (e.g., 5G-CN) may provide/configure the wireless device(s) 156 with one
or more interfaces to one or more DNs 170, such as public DNs (e.g., the Internet),
private DNs, and/or intra-operator DNs. As part of the interface functionality, the
CN 152 (e.g., 5G-CN) may set up end-to-end connections between the wireless device(s)
156 and the one or more DNs, authenticate the wireless device(s) 156, and/or provide/configure
charging functionality. The CN 152 (e.g., the 5G-CN) may be a service-based architecture,
which may differ from other CNs (e.g., such as a 3GPP 4G CN). The architecture of
nodes of the CN 152 (e.g., 5G-CN) may be defined as network functions that offer services
via interfaces to other network functions. The network functions of the CN 152 (e.g.,
5G CN) may be implemented in several ways, for example, as network elements on dedicated
or shared hardware, as software instances running on dedicated or shared hardware,
and/or as virtualized functions instantiated on a platform (e.g., a cloud-based platform).
[0018] The CN 152 (e.g., 5G-CN) may comprise an Access and Mobility Management Function
(AMF) device 158A and/or a User Plane Function (UPF) device 158B, which may be separate
components or one component AMF/UPF device 158. The UPF device 158B may serve as a
gateway between a RAN 154 (e.g., NG-RAN) and the one or more DNs 170. The UPF device
158B may perform functions, such as: packet routing and forwarding, packet inspection
and user plane policy rule enforcement, traffic usage reporting, uplink classification
to support routing of traffic flows to the one or more DNs 170, quality of service
(QoS) handling for the user plane (e.g., packet filtering, gating, uplink/downlink
rate enforcement, and uplink traffic verification), downlink packet buffering, and/or
downlink data notification triggering. The UPF device 158B may serve as an anchor
point for intra-/inter-Radio Access Technology (RAT) mobility, an external protocol
(or packet) data unit (PDU) session point of interconnect to the one or more DNs,
and/or a branching point to support a multi-homed PDU session. The wireless device(s)
156 may be configured to receive services via a PDU session, which may be a logical
connection between a wireless device and a DN.
[0019] The AMF device 158A may perform functions, such as: Non-Access Stratum (NAS) signaling
termination, NAS signaling security, Access Stratum (AS) security control, inter-CN
node signaling for mobility between access networks (e.g., 3GPP access networks and/or
non-3GPP networks), idle mode wireless device reachability (e.g., idle mode UE reachability
for control and execution of paging retransmission), registration area management,
intra-system and inter-system mobility support, access authentication, access authorization
including checking of roaming rights, mobility management control (e.g., subscription
and policies), network slicing support, and/or session management function (SMF) selection.
NAS may refer to the functionality operating between a CN and a wireless device, and
AS may refer to the functionality operating between a wireless device and a RAN.
[0020] The CN 152 (e.g., 5G-CN) may comprise one or more additional network functions that
may not be shown in FIG. 1B. The CN 152 (e.g., 5G-CN) may comprise one or more devices
implementing at least one of: a Session Management Function (SMF), an NR Repository
Function (NRF), a Policy Control Function (PCF), a Network Exposure Function (NEF),
a Unified Data Management (UDM), an Application Function (AF), an Authentication Server
Function (AUSF), and/or any other function.
[0021] The RAN 154 (e.g., NG-RAN) may communicate with the wireless device(s) 156 via radio
communications (e.g., an over the air interface). The wireless device(s) 156 may communicate
with the CN 152 via the RAN 154. The RAN 154 (e.g., NG-RAN) may comprise one or more
first-type base stations (e.g., gNBs comprising a gNB 160A and a gNB 160B (collectively
gNBs 160)) and/or one or more second-type base stations (e.g., ng eNBs comprising
an ng-eNB 162A and an ng-eNB 162B (collectively ng eNBs 162)). The RAN 154 may comprise
one or more of any quantity of types of base station. The gNBs 160 and ng eNBs 162
may be referred to as base stations. The base stations (e.g., the gNBs 160 and ng
eNBs 162) may comprise one or more sets of antennas for communicating with the wireless
device(s) 156 wirelessly (e.g., an over an air interface). One or more base stations
(e.g., the gNBs 160 and/or the ng eNBs 162) may comprise multiple sets of antennas
to respectively control multiple cells (or sectors). The cells of the base stations
(e.g., the gNBs 160 and the ng-eNBs 162) may provide a radio coverage to the wireless
device(s) 156 over a wide geographic area to support wireless device mobility.
[0022] The base stations (e.g., the gNBs 160 and/or the ng-eNBs 162) may be connected to
the CN 152 (e.g., 5G CN) via a first interface (e.g., an NG interface) and to other
base stations via a second interface (e.g., an Xn interface). The NG and Xn interfaces
may be established using direct physical connections and/or indirect connections over
an underlying transport network, such as an internet protocol (IP) transport network.
The base stations (e.g., the gNBs 160 and/or the ng-eNBs 162) may communicate with
the wireless device(s) 156 via a third interface (e.g., a Uu interface). A base station
(e.g., the gNB 160A) may communicate with the wireless device 156A via a Uu interface.
The NG, Xn, and Uu interfaces may be associated with a protocol stack. The protocol
stacks associated with the interfaces may be used by the network elements shown in
FIG. 1B to exchange data and signaling messages. The protocol stacks may comprise
two planes: a user plane and a control plane. Any other quantity of planes may be
used (e.g., in a protocol stack). The user plane may handle data of interest to a
user. The control plane may handle signaling messages of interest to the network elements.
[0023] One or more base stations (e.g., the gNBs 160 and/or the ng-eNBs 162) may communicate
with one or more AMF/UPF devices, such as the AMF/UPF 158, via one or more interfaces
(e.g., NG interfaces). A base station (e.g., the gNB 160A) may be in communication
with, and/or connected to, the UPF 158B of the AMF/UPF 158 via an NG-User plane (NG-U)
interface. The NG-U interface may provide/perform delivery (e.g., non-guaranteed delivery)
of user plane PDUs between a base station (e.g., the gNB 160A) and a UPF device (e.g.,
the UPF 158B). The base station (e.g., the gNB 160A) may be in communication with,
and/or connected to, an AMF device (e.g., the AMF 158A) via an NG-Control plane (NG-C)
interface. The NG-C interface may provide/perform, for example, NG interface management,
wireless device context management (e.g., UE context management), wireless device
mobility management (e.g., UE mobility management), transport of NAS messages, paging,
PDU session management, configuration transfer, and/or warning message transmission.
[0024] A wireless device may access the base station, via an interface (e.g., Uu interface),
for the user plane configuration and the control plane configuration. The base stations
(e.g., gNBs 160) may provide user plane and control plane protocol terminations towards
the wireless device(s) 156 via the Uu interface. A base station (e.g., the gNB 160A)
may provide user plane and control plane protocol terminations toward the wireless
device 156A over a Uu interface associated with a first protocol stack. A base station
(e.g., the ng-eNBs 162) may provide Evolved UMTS Terrestrial Radio Access (E UTRA)
user plane and control plane protocol terminations towards the wireless device(s)
156 via a Uu interface (e.g., where E UTRA may refer to the 3GPP 4G radio-access technology).
A base station (e.g., the ng-eNB 162B) may provide E UTRA user plane and control plane
protocol terminations towards the wireless device 156B via a Uu interface associated
with a second protocol stack. The user plane and control plane protocol terminations
may comprise, for example, NR user plane and control plane protocol terminations,
4G user plane and control plane protocol terminations, etc.
[0025] The CN 152 (e.g., 5G-CN) may be configured to handle one or more radio accesses (e.g.,
NR, 4G, and/or any other radio accesses). It may also be possible for an NR network/device
(or any first network/device) to connect to a 4G core network/device (or any second
network/device) in a non-standalone mode (e.g., non-standalone operation). In a non-standalone
mode/operation, a 4G core network may be used to provide (or at least support) control-plane
functionality (e.g., initial access, mobility, and/or paging). Although only one AMF/UPF
158 is shown in FIG. 1B, one or more base stations (e.g., one or more gNBs and/or
one or more ng-eNBs) may be connected to multiple AMF/UPF nodes, for example, to provide
redundancy and/or to load share across the multiple AMF/UPF nodes.
[0026] An interface (e.g., Uu, Xn, and/or NG interfaces) between network elements (e.g.,
the network elements shown in FIG. 1B) may be associated with a protocol stack that
the network elements may use to exchange data and signaling messages. A protocol stack
may comprise two planes: a user plane and a control plane. Any other quantity of planes
may be used (e.g., in a protocol stack). The user plane may handle data associated
with a user (e.g., data of interest to a user). The control plane may handle data
associated with one or more network elements (e.g., signaling messages of interest
to the network elements).
[0027] The communication network 100 in FIG. 1A and/or the communication network 150 in
FIG. 1B may comprise any quantity/number and/or type of devices, such as, for example,
computing devices, wireless devices, mobile devices, handsets, tablets, laptops, internet
of things (IoT) devices, hotspots, cellular repeaters, computing devices, and/or,
more generally, user equipment (e.g., UE). Although one or more of the above types
of devices may be referenced herein (e.g., UE, wireless device, computing device,
etc.), it should be understood that any device herein may comprise any one or more
of the above types of devices or similar devices. The communication network, and any
other network referenced herein, may comprise an LTE network, a 5G network, a satellite
network, and/or any other network for wireless communications (e.g., any 3GPP network
and/or any non-3GPP network). Apparatuses, systems, and/or methods described herein
may generally be described as implemented on one or more devices (e.g., wireless device,
base station, eNB, gNB, computing device, etc.), in one or more networks, but it will
be understood that one or more features and steps may be implemented on any device
and/or in any network.
[0028] FIG. 2A shows an example user plane configuration. The user plane configuration may
comprise, for example, an NR user plane protocol stack. FIG. 2B shows an example control
plane configuration. The control plane configuration may comprise, for example, an
NR control plane protocol stack. One or more of the user plane configuration and/or
the control plane configuration may use a Uu interface that may be between a wireless
device 210 and a base station 220. The protocol stacks shown in FIG. 2A and FIG. 2B
may be substantially the same or similar to those used for the Uu interface between,
for example, the wireless device 156A and the base station 160A shown in FIG. 1B.
[0029] A user plane configuration (e.g., an NR user plane protocol stack) may comprise multiple
layers (e.g., five layers or any other quantity of layers) implemented in the wireless
device 210 and the base station 220 (e.g., as shown in FIG. 2A). At the bottom of
the protocol stack, physical layers (PHYs) 211 and 221 may provide transport services
to the higher layers of the protocol stack and may correspond to layer 1 of the Open
Systems Interconnection (OSI) model. The protocol layers above PHY 211 may comprise
a medium access control layer (MAC) 212, a radio link control layer (RLC) 213, a packet
data convergence protocol layer (PDCP) 214, and/or a service data application protocol
layer (SDAP) 215. The protocol layers above PHY 221 may comprise a medium access control
layer (MAC) 222, a radio link control layer (RLC) 223, a packet data convergence protocol
layer (PDCP) 224, and/or a service data application protocol layer (SDAP) 225. One
or more of the four protocol layers above PHY 211 may correspond to layer 2, or the
data link layer, of the OSI model. One or more of the four protocol layers above PHY
221 may correspond to layer 2, or the data link layer, of the OSI model.
[0030] FIG. 3 shows an example of protocol layers. The protocol layers may comprise, for
example, protocol layers of the NR user plane protocol stack. One or more services
may be provided between protocol layers. SDAPs (e.g., SDAPS 215 and 225 shown in FIG.
2A and FIG. 3) may perform Quality of Service (QoS) flow handling. A wireless device
(e.g., the wireless devices 106, 156A, 156B, and 210) may receive services through/via
a PDU session, which may be a logical connection between the wireless device and a
DN. The PDU session may have one or more QoS flows 310. A UPF (e.g., the UPF 158B)
of a CN may map IP packets to the one or more QoS flows of the PDU session, for example,
based on one or more QoS requirements (e.g., in terms of delay, data rate, error rate,
and/or any other quality/service requirement). The SDAPs 215 and 225 may perform mapping/demapping
between the one or more QoS flows 310 and one or more radio bearers 320 (e.g., data
radio bearers). The mapping/de-mapping between the one or more QoS flows 310 and the
radio bearers 320 may be determined by the SDAP 225 of the base station 220. The SDAP
215 of the wireless device 210 may be informed of the mapping between the QoS flows
310 and the radio bearers 320 via reflective mapping and/or control signaling received
from the base station 220. For reflective mapping, the SDAP 225 of the base station
220 may mark the downlink packets with a QoS flow indicator (QFI), which may be monitored/detected/identified/indicated/observed
by the SDAP 215 of the wireless device 210 to determine the mapping/de-mapping between
the one or more QoS flows 310 and the radio bearers 320.
[0031] PDCPs (e.g., the PDCPs 214 and 224 shown in FIG. 2A and FIG. 3) may perform header
compression/decompression, for example, to reduce the amount of data that may need
to be transmitted over the air interface, ciphering/deciphering to prevent unauthorized
decoding of data transmitted over the air interface, and/or integrity protection (e.g.,
to ensure control messages originate from intended sources). The PDCPs 214 and 224
may perform retransmissions of undelivered packets, in-sequence delivery and reordering
of packets, and/or removal of packets received in duplicate due to, for example, a
handover (e.g., an intra-gNB handover). The PDCPs 214 and 224 may perform packet duplication,
for example, to improve the likelihood of the packet being received. A receiver may
receive the packet in duplicate and may remove any duplicate packets. Packet duplication
may be useful for certain services, such as services that require high reliability.
[0032] The PDCP layers (e.g., PDCPs 214 and 224) may perform mapping/de-mapping between
a split radio bearer and RLC channels (e.g., RLC channels 330) (e.g., in a dual connectivity
scenario/configuration). Dual connectivity may refer to a technique that allows a
wireless device to communicate with multiple cells (e.g., two cells) or, more generally,
multiple cell groups comprising: a master cell group (MCG) and a secondary cell group
(SCG). A split bearer may be configured and/or used, for example, if a single radio
bearer (e.g., such as one of the radio bearers provided/configured by the PDCPs 214
and 224 as a service to the SDAPs 215 and 225) is handled by cell groups in dual connectivity.
The PDCPs 214 and 224 may map/de-map between the split radio bearer and RLC channels
330 belonging to the cell groups.
[0033] RLC layers (e.g., RLCs 213 and 223) may perform segmentation, retransmission via
Automatic Repeat Request (ARQ), and/or removal of duplicate data units received from
MAC layers (e.g., MACs 212 and 222, respectively). The RLC layers (e.g., RLCs 213
and 223) may support multiple transmission modes (e.g., three transmission modes:
transparent mode (TM); unacknowledged mode (UM); and acknowledged mode (AM)). The
RLC layers may perform one or more of the noted functions, for example, based on the
transmission mode an RLC layer is operating. The RLC configuration may be per logical
channel. The RLC configuration may not depend on numerologies and/or Transmission
Time Interval (TTI) durations (or other durations). The RLC layers (e.g., RLCs 213
and 223) may provide/configure RLC channels as a service to the PDCP layers (e.g.,
PDCPs 214 and 224, respectively), such as shown in FIG. 3.
[0034] The MAC layers (e.g., MACs 212 and 222) may perform multiplexing/demultiplexing of
logical channels and/or mapping between logical channels and transport channels. The
multiplexing/demultiplexing may comprise multiplexing/demultiplexing of data units/data
portions, belonging to the one or more logical channels, into/from Transport Blocks
(TBs) delivered to/from the PHY layers (e.g., PHYs 211 and 221, respectively). The
MAC layer of a base station (e.g., MAC 222) may be configured to perform scheduling,
scheduling information reporting, and/or priority handling between wireless devices
via dynamic scheduling. Scheduling may be performed by a base station (e.g., the base
station 220 at the MAC 222) for downlink/or and uplink. The MAC layers (e.g., MACs
212 and 222) may be configured to perform error correction(s) via Hybrid Automatic
Repeat Request (HARQ) (e.g., one HARQ entity per carrier in case of Carrier Aggregation
(CA)), priority handling between logical channels of the wireless device 210 via logical
channel prioritization and/or padding. The MAC layers (e.g., MACs 212 and 222) may
support one or more numerologies and/or transmission timings. Mapping restrictions
in a logical channel prioritization may control which numerology and/or transmission
timing a logical channel may use. The MAC layers (e.g., the MACs 212 and 222) may
provide/configure logical channels 340 as a service to the RLC layers (e.g., the RLCs
213 and 223).
[0035] The PHY layers (e.g., PHYs 211 and 221) may perform mapping of transport channels
to physical channels and/or digital and analog signal processing functions, for example,
for sending and/or receiving information (e.g., via an over the air interface). The
digital and/or analog signal processing functions may comprise, for example, coding/decoding
and/or modulation/demodulation. The PHY layers (e.g., PHYs 211 and 221) may perform
multi-antenna mapping. The PHY layers (e.g., the PHYs 211 and 221) may provide/configure
one or more transport channels (e.g., transport channels 350) as a service to the
MAC layers (e.g., the MACs 212 and 222, respectively).
[0036] FIG. 4A shows an example downlink data flow for a user plane configuration. The user
plane configuration may comprise, for example, the NR user plane protocol stack shown
in FIG. 2A. One or more TBs may be generated, for example, based on a data flow via
a user plane protocol stack. As shown in FIG. 4A, a downlink data flow of three IP
packets (n, n+1, and m) via the NR user plane protocol stack may generate two TBs
(e.g., at the base station 220). An uplink data flow via the NR user plane protocol
stack may be similar to the downlink data flow shown in FIG. 4A. The three IP packets
(n, n+1, and m) may be determined from the two TBs, for example, based on the uplink
data flow via an NR user plane protocol stack. A first quantity of packets (e.g.,
three or any other quantity) may be determined from a second quantity of TBs (e.g.,
two or another quantity).
[0037] The downlink data flow may begin, for example, if the SDAP 225 receives the three
IP packets (or other quantity of IP packets) from one or more QoS flows and maps the
three packets (or other quantity of packets) to radio bearers (e.g., radio bearers
402 and 404). The SDAP 225 may map the IP packets n and n+1 to a first radio bearer
402 and map the IP packet m to a second radio bearer 404. An SDAP header (labeled
with "H" preceding each SDAP SDU shown in FIG. 4A) may be added to an IP packet to
generate an SDAP PDU, which may be referred to as a PDCP SDU. The data unit transferred
from/to a higher protocol layer may be referred to as a service data unit (SDU) of
the lower protocol layer, and the data unit transferred to/from a lower protocol layer
may be referred to as a protocol data unit (PDU) of the higher protocol layer. As
shown in FIG. 4A, the data unit from the SDAP 225 may be an SDU of lower protocol
layer PDCP 224 (e.g., PDCP SDU) and may be a PDU of the SDAP 225 (e.g., SDAP PDU).
[0038] Each protocol layer (e.g., protocol layers shown in FIG. 4A) or at least some protocol
layers may: perform its own function(s) (e.g., one or more functions of each protocol
layer described with respect to FIG. 3), add a corresponding header, and/or forward
a respective output to the next lower layer (e.g., its respective lower layer). The
PDCP 224 may perform an IP-header compression and/or ciphering. The PDCP 224 may forward
its output (e.g., a PDCP PDU, which is an RLC SDU) to the RLC 223. The RLC 223 may
optionally perform segmentation (e.g., as shown for IP packet m in FIG. 4A). The RLC
223 may forward its outputs (e.g., two RLC PDUs, which are two MAC SDUs, generated
by adding respective subheaders to two SDU segments (SDU Segs)) to the MAC 222. The
MAC 222 may multiplex a number of RLC PDUs (MAC SDUs). The MAC 222 may attach a MAC
subheader to an RLC PDU (MAC SDU) to form a TB. The MAC subheaders may be distributed
across the MAC PDU (e.g., in an NR configuration as shown in FIG. 4A). The MAC subheaders
may be entirely located at the beginning of a MAC PDU (e.g., in an LTE configuration).
The NR MAC PDU structure may reduce a processing time and/or associated latency, for
example, if the MAC PDU subheaders are computed before assembling the full MAC PDU.
[0039] FIG. 4B shows an example format of a MAC subheader in a MAC PDU. A MAC PDU may comprise
a MAC subheader (H) and a MAC SDU. Each of one or more MAC subheaders may comprise
an SDU length field for indicating the length (e.g., in bytes) of the MAC SDU to which
the MAC subheader corresponds; a logical channel identifier (LCID) field for identifying/indicating
the logical channel from which the MAC SDU originated to aid in the demultiplexing
process; a flag (F) for indicating the size of the SDU length field; and a reserved
bit (R) field for future use.
[0040] One or more MAC control elements (CEs) may be added to, or inserted into, the MAC
PDU by a MAC layer, such as MAC 223 or MAC 222. As shown in FIG. 4B, two MAC CEs may
be inserted/added before two MAC PDUs. The MAC CEs may be inserted/added at the beginning
of a MAC PDU for downlink transmissions (as shown in FIG. 4B). One or more MAC CEs
may be inserted/added at the end of a MAC PDU for uplink transmissions. MAC CEs may
be used for in band control signaling. Example MAC CEs may comprise scheduling-related
MAC CEs, such as buffer status reports and power headroom reports; activation/deactivation
MAC CEs (e.g., MAC CEs for activation/deactivation of PDCP duplication detection,
channel state information (CSI) reporting, sounding reference signal (SRS) transmission,
and prior configured components); discontinuous reception (DRX)-related MAC CEs; timing
advance MAC CEs; and random access-related MAC CEs. A MAC CE may be preceded by a
MAC subheader with a similar format as described for the MAC subheader for MAC SDUs
and may be identified with a reserved value in the LCID field that indicates the type
of control information included in the corresponding MAC CE.
[0041] FIG. 5A shows an example mapping for downlink channels. The mapping for uplink channels
may comprise mapping between channels (e.g., logical channels, transport channels,
and physical channels) for downlink. FIG. 5B shows an example mapping for uplink channels.
The mapping for uplink channels may comprise mapping between channels (e.g., logical
channels, transport channels, and physical channels) for uplink. Information may be
passed through/via channels between the RLC, the MAC, and the PHY layers of a protocol
stack (e.g., the NR protocol stack). A logical channel may be used between the RLC
and the MAC layers. The logical channel may be classified/indicated as a control channel
that may carry control and/or configuration information (e.g., in the NR control plane),
or as a traffic channel that may carry data (e.g., in the NR user plane). A logical
channel may be classified/indicated as a dedicated logical channel that may be dedicated
to a specific wireless device, and/or as a common logical channel that may be used
by more than one wireless device (e.g., a group of wireless devices).
[0042] A logical channel may be defined by the type of information it carries. The set of
logical channels (e.g., in an NR configuration) may comprise one or more channels
described below. A paging control channel (PCCH) may comprise/carry one or more paging
messages used to page a wireless device whose location is not known to the network
on a cell level. A broadcast control channel (BCCH) may comprise/carry system information
messages in the form of a master information block (MIB) and several system information
blocks (SIBs). The system information messages may be used by wireless devices to
obtain information about how a cell is configured and how to operate within the cell.
A common control channel (CCCH) may comprise/carry control messages together with
random access. A dedicated control channel (DCCH) may comprise/carry control messages
to/from a specific wireless device to configure the wireless device with configuration
information. A dedicated traffic channel (DTCH) may comprise/carry user data to/from
a specific wireless device.
[0043] Transport channels may be used between the MAC and PHY layers. Transport channels
may be defined by how the information they carry is sent/transmitted (e.g., via an
over the air interface). The set of transport channels (e.g., that may be defined
by an NR configuration or any other configuration) may comprise one or more of the
following channels. A paging channel (PCH) may comprise/carry paging messages that
originated from the PCCH. A broadcast channel (BCH) may comprise/carry the MIB from
the BCCH. A downlink shared channel (DL-SCH) may comprise/carry downlink data and
signaling messages, including the SIBs from the BCCH. An uplink shared channel (UL-SCH)
may comprise/carry uplink data and signaling messages. A random access channel (RACH)
may provide a wireless device with an access to the network without any prior scheduling.
[0044] The PHY layer may use physical channels to pass/transfer information between processing
levels of the PHY layer. A physical channel may have an associated set of time-frequency
resources for carrying the information of one or more transport channels. The PHY
layer may generate control information to support the low-level operation of the PHY
layer. The PHY layer may provide/transfer the control information to the lower levels
of the PHY layer via physical control channels (e.g., referred to as L1/L2 control
channels). The set of physical channels and physical control channels (e.g., that
may be defined by an NR configuration or any other configuration) may comprise one
or more of the following channels. A physical broadcast channel (PBCH) may comprise/carry
the MIB from the BCH. A physical downlink shared channel (PDSCH) may comprise/carry
downlink data and signaling messages from the DL-SCH, as well as paging messages from
the PCH. A physical downlink control channel (PDCCH) may comprise/carry downlink control
information (DCI), which may comprise downlink scheduling commands, uplink scheduling
grants, and uplink power control commands. A physical uplink shared channel (PUSCH)
may comprise/carry uplink data and signaling messages from the UL-SCH and in some
instances uplink control information (UCI) as described below. A physical uplink control
channel (PUCCH) may comprise/carry UCI, which may comprise HARQ acknowledgments, channel
quality indicators (CQI), pre-coding matrix indicators (PMI), rank indicators (RI),
and scheduling requests (SR). A physical random access channel (PRACH) may be used
for random access.
[0045] The physical layer may generate physical signals to support the low-level operation
of the physical layer, which may be similar to the physical control channels. As shown
in FIG. 5A and FIG. 5B, the physical layer signals (e.g., that may be defined by an
NR configuration or any other configuration) may comprise primary synchronization
signals (PSS), secondary synchronization signals (SSS), channel state information
reference signals (CSI-RS), demodulation reference signals (DM-RS), sounding reference
signals (SRS), phase-tracking reference signals (PT RS), and/or any other signals.
[0046] One or more of the channels (e.g., logical channels, transport channels, physical
channels, etc.) may be used to carry out functions associated with the control plan
protocol stack (e.g., NR control plane protocol stack). FIG. 2B shows an example control
plane configuration (e.g., an NR control plane protocol stack). As shown in FIG. 2B,
the control plane configuration (e.g., the NR control plane protocol stack) may use
substantially the same/similar one or more protocol layers (e.g., PHY 211 and 221,
MAC 212 and 222, RLC 213 and 223, and PDCP 214 and 224) as the example user plane
configuration (e.g., the NR user plane protocol stack). Similar four protocol layers
may comprise the PHYs 211 and 221, the MACs 212 and 222, the RLCs 213 and 223, and
the PDCPs 214 and 224. The control plane configuration (e.g., the NR control plane
stack) may have radio resource controls (RRCs) 216 and 226 and NAS protocols 217 and
237 at the top of the control plane configuration (e.g., the NR control plane protocol
stack), for example, instead of having the SDAPs 215 and 225. The control plane configuration
may comprise an AMF 230 comprising the NAS protocol 237.
[0047] The NAS protocols 217 and 237 may provide control plane functionality between the
wireless device 210 and the AMF 230 (e.g., the AMF 158A or any other AMF) and/or,
more generally, between the wireless device 210 and a CN (e.g., the CN 152 or any
other CN). The NAS protocols 217 and 237 may provide control plane functionality between
the wireless device 210 and the AMF 230 via signaling messages, referred to as NAS
messages. There may be no direct path between the wireless device 210 and the AMF
230 via which the NAS messages may be transported. The NAS messages may be transported
using the AS of the Uu and NG interfaces. The NAS protocols 217 and 237 may provide
control plane functionality, such as authentication, security, a connection setup,
mobility management, session management, and/or any other functionality.
[0048] The RRCs 216 and 226 may provide/configure control plane functionality between the
wireless device 210 and the base station 220 and/or, more generally, between the wireless
device 210 and the RAN (e.g., the base station 220). The RRC layers 216 and 226 may
provide/configure control plane functionality between the wireless device 210 and
the base station 220 via signaling messages, which may be referred to as RRC messages.
The RRC messages may be sent/transmitted between the wireless device 210 and the RAN
(e.g., the base station 220) using signaling radio bearers and the same/similar PDCP,
RLC, MAC, and PHY protocol layers. The MAC layer may multiplex control-plane and user-plane
data into the same TB. The RRC layers 216 and 226 may provide/configure control plane
functionality, such as one or more of the following functionalities: broadcast of
system information related to AS and NAS; paging initiated by the CN or the RAN; establishment,
maintenance and release of an RRC connection between the wireless device 210 and the
RAN (e.g., the base station 220); security functions including key management; establishment,
configuration, maintenance and release of signaling radio bearers and data radio bearers;
mobility functions; QoS management functions; wireless device measurement reporting
(e.g., the wireless device measurement reporting) and control of the reporting; detection
of and recovery from radio link failure (RLF); and/or NAS message transfer. As part
of establishing an RRC connection, RRC layers 216 and 226 may establish an RRC context,
which may involve configuring parameters for communication between the wireless device
210 and the RAN (e.g., the base station 220).
[0049] FIG. 6 shows example RRC states and RRC state transitions. An RRC state of a wireless
device may be changed to another RRC state (e.g., RRC state transitions of a wireless
device). The wireless device may be substantially the same or similar to the wireless
device 106, 210, or any other wireless device. A wireless device may be in at least
one of a plurality of states, such as three RRC states comprising RRC connected 602
(e.g., RRC CONNECTED), RRC idle 606 (e.g., RRC IDLE), and RRC inactive 604 (e.g.,
RRC_INACTIVE). The RRC inactive 604 may be RRC connected but inactive.
[0050] An RRC connection may be established for the wireless device. For example, this may
be during an RRC connected state. During the RRC connected state (e.g., during the
RRC connected 602), the wireless device may have an established RRC context and may
have at least one RRC connection with a base station. The base station may be similar
to one of the one or more base stations (e.g., one or more base stations of the RAN
104 shown in FIG. 1A, one of the gNBs 160 or ng-eNBs 162 shown in FIG. 1B, the base
station 220 shown in FIG. 2A and FIG. 2B, or any other base stations). The base station
with which the wireless device is connected (e.g., has established an RRC connection)
may have the RRC context for the wireless device. The RRC context, which may be referred
to as a wireless device context (e.g., the UE context), may comprise parameters for
communication between the wireless device and the base station. These parameters may
comprise, for example, one or more of: AS contexts; radio link configuration parameters;
bearer configuration information (e.g., relating to a data radio bearer, a signaling
radio bearer, a logical channel, a QoS flow, and/or a PDU session); security information;
and/or layer configuration information (e.g., PHY, MAC, RLC, PDCP, and/or SDAP layer
configuration information). During the RRC connected state (e.g., the RRC connected
602), mobility of the wireless device may be managed/controlled by an RAN (e.g., the
RAN 104 or the NG RAN 154). The wireless device may measure received signal levels
(e.g., reference signal levels, reference signal received power, reference signal
received quality, received signal strength indicator, etc.) based on one or more signals
sent from a serving cell and neighboring cells. The wireless device may report these
measurements to a serving base station (e.g., the base station currently serving the
wireless device). The serving base station of the wireless device may request a handover
to a cell of one of the neighboring base stations, for example, based on the reported
measurements. The RRC state may transition from the RRC connected state (e.g., RRC
connected 602) to an RRC idle state (e.g., the RRC idle 606) via a connection release
procedure 608. The RRC state may transition from the RRC connected state (e.g., RRC
connected 602) to the RRC inactive state (e.g., RRC inactive 604) via a connection
inactivation procedure 610.
[0051] An RRC context may not be established for the wireless device. For example, this
may be during the RRC idle state. During the RRC idle state (e.g., the RRC idle 606),
an RRC context may not be established for the wireless device. During the RRC idle
state (e.g., the RRC idle 606), the wireless device may not have an RRC connection
with the base station. During the RRC idle state (e.g., the RRC idle 606), the wireless
device may be in a sleep state for the majority of the time (e.g., to conserve battery
power). The wireless device may wake up periodically (e.g., each discontinuous reception
(DRX) cycle) to monitor for paging messages (e.g., paging messages set from the RAN).
Mobility of the wireless device may be managed by the wireless device via a procedure
of a cell reselection. The RRC state may transition from the RRC idle state (e.g.,
the RRC idle 606) to the RRC connected state (e.g., the RRC connected 602) via a connection
establishment procedure 612, which may involve a random access procedure.
[0052] A previously established RRC context may be maintained for the wireless device. For
example, this may be during the RRC inactive state. During the RRC inactive state
(e.g., the RRC inactive 604), the RRC context previously established may be maintained
in the wireless device and the base station. The maintenance of the RRC context may
enable/allow a fast transition to the RRC connected state (e.g., the RRC connected
602) with reduced signaling overhead as compared to the transition from the RRC idle
state (e.g., the RRC idle 606) to the RRC connected state (e.g., the RRC connected
602). During the RRC inactive state (e.g., the RRC inactive 604), the wireless device
may be in a sleep state and mobility of the wireless device may be managed/controlled
by the wireless device via a cell reselection. The RRC state may transition from the
RRC inactive state (e.g., the RRC inactive 604) to the RRC connected state (e.g.,
the RRC connected 602) via a connection resume procedure 614. The RRC state may transition
from the RRC inactive state (e.g., the RRC inactive 604) to the RRC idle state (e.g.,
the RRC idle 606) via a connection release procedure 616 that may be the same as or
similar to connection release procedure 608.
[0053] An RRC state may be associated with a mobility management mechanism. During the RRC
idle state (e.g., RRC idle 606) and the RRC inactive state (e.g., the RRC inactive
604), mobility may be managed/controlled by the wireless device via a cell reselection.
The purpose of mobility management during the RRC idle state (e.g., the RRC idle 606)
or during the RRC inactive state (e.g., the RRC inactive 604) may be to enable/allow
the network to be able to notify the wireless device of an event via a paging message
without having to broadcast the paging message over the entire mobile communications
network. The mobility management mechanism used during the RRC idle state (e.g., the
RRC idle 606) or during the RRC idle state (e.g., the RRC inactive 604) may enable/allow
the network to track the wireless device on a cell-group level, for example, so that
the paging message may be broadcast over the cells of the cell group that the wireless
device currently resides within (e.g. instead of sending the paging message over the
entire mobile communication network). The mobility management mechanisms for the RRC
idle state (e.g., the RRC idle 606) and the RRC inactive state (e.g., the RRC inactive
604) may track the wireless device on a cell-group level. The mobility management
mechanisms may do the tracking, for example, using different granularities of grouping.
There may be a plurality of levels of cell-grouping granularity (e.g., three levels
of cell-grouping granularity: individual cells; cells within a RAN area identified
by a RAN area identifier (RAI); and cells within a group of RAN areas, referred to
as a tracking area and identified by a tracking area identifier (TAI)).
[0054] Tracking areas may be used to track the wireless device (e.g., tracking the location
of the wireless device at the CN level). The CN (e.g., the CN 102, the 5G CN 152,
or any other CN) may send to the wireless device a list of TAIs associated with a
wireless device registration area (e.g., a UE registration area). A wireless device
may perform a registration update with the CN to allow the CN to update the location
of the wireless device and provide the wireless device with a new the UE registration
area, for example, if the wireless device moves (e.g., via a cell reselection) to
a cell associated with a TAI that may not be included in the list of TAIs associated
with the UE registration area.
[0055] RAN areas may be used to track the wireless device (e.g., the location of the wireless
device at the RAN level). For a wireless device in an RRC inactive state (e.g., the
RRC inactive 604), the wireless device may be assigned/provided/configured with a
RAN notification area. A RAN notification area may comprise one or more cell identities
(e.g., a list of RAIs and/or a list of TAIs). A base station may belong to one or
more RAN notification areas. A cell may belong to one or more RAN notification areas.
A wireless device may perform a notification area update with the RAN to update the
RAN notification area of the wireless device, for example, if the wireless device
moves (e.g., via a cell reselection) to a cell not included in the RAN notification
area assigned/provided/configured to the wireless device.
[0056] A base station storing an RRC context for a wireless device or a last serving base
station of the wireless device may be referred to as an anchor base station. An anchor
base station may maintain an RRC context for the wireless device at least during a
period of time that the wireless device stays in a RAN notification area of the anchor
base station and/or during a period of time that the wireless device stays in an RRC
inactive state (e.g., RRC inactive 604).
[0057] A base station (e.g., gNBs 160 in FIG. 1B or any other base station) may be split
in two parts: a central unit (e.g., a base station central unit, such as a gNB CU)
and one or more distributed units (e.g., a base station distributed unit, such as
a gNB DU). A base station central unit (CU) may be coupled to one or more base station
distributed units (DUs) using an F1 interface (e.g., an F1 interface defined in an
NR configuration). The base station CU may comprise the RRC, the PDCP, and the SDAP
layers. A base station distributed unit (DU) may comprise the RLC, the MAC, and the
PHY layers.
[0058] The physical signals and physical channels (e.g., described with respect to FIG.
5A and FIG. 5B) may be mapped onto one or more symbols (e.g., orthogonal frequency
divisional multiplexing (OFDM) symbols in an NR configuration or any other symbols).
OFDM is a multicarrier communication scheme that sends/transmits data over F orthogonal
subcarriers (or tones). The data may be mapped to a series of complex symbols (e.g.,
M-quadrature amplitude modulation (M-QAM) symbols or M-phase shift keying (M PSK)
symbols or any other modulated symbols), referred to as source symbols, and divided
into F parallel symbol streams, for example, before transmission of the data. The
F parallel symbol streams may be treated as if they are in the frequency domain. The
F parallel symbols may be used as inputs to an Inverse Fast Fourier Transform (IFFT)
block that transforms them into the time domain. The IFFT block may take in F source
symbols at a time, one from each of the F parallel symbol streams. The IFFT block
may use each source symbol to modulate the amplitude and phase of one of F sinusoidal
basis functions that correspond to the F orthogonal subcarriers. The output of the
IFFT block may be F time-domain samples that represent the summation of the F orthogonal
subcarriers. The F time-domain samples may form a single OFDM symbol. An OFDM symbol
provided/output by the IFFT block may be sent/transmitted over the air interface on
a carrier frequency, for example, after one or more processes (e.g., addition of a
cyclic prefix) and up-conversion. The F parallel symbol streams may be mixed, for
example, using a Fast Fourier Transform (FFT) block before being processed by the
IFFT block. This operation may produce Discrete Fourier Transform (DFT)-precoded OFDM
symbols and may be used by one or more wireless devices in the uplink to reduce the
peak to average power ratio (PAPR). Inverse processing may be performed on the OFDM
symbol at a receiver using an FFT block to recover the data mapped to the source symbols.
[0059] FIG. 7 shows an example configuration of a frame. The frame may comprise, for example,
an NR radio frame into which OFDM symbols may be grouped. A frame (e.g., an NR radio
frame) may be identified/indicated by a system frame number (SFN) or any other value.
The SFN may repeat with a period of 1024 frames. One NR frame may be 10 milliseconds
(ms) in duration and may comprise 10 subframes that are 1 ms in duration. A subframe
may be divided into one or more slots (e.g., depending on numerologies and/or different
subcarrier spacings). Each of the one or more slots may comprise, for example, 14
OFDM symbols per slot. Any quantity of symbols, slots, or duration may be used for
any time interval.
[0060] The duration of a slot may depend on the numerology used for the OFDM symbols of
the slot. A flexible numerology may be supported, for example, to accommodate different
deployments (e.g., cells with carrier frequencies below 1 GHz up to cells with carrier
frequencies in the mm-wave range). A flexible numerology may be supported, for example,
in an NR configuration or any other radio configurations. A numerology may be defined
in terms of subcarrier spacing and/or cyclic prefix duration. Subcarrier spacings
may be scaled up by powers of two from a baseline subcarrier spacing of 15 kHz. Cyclic
prefix durations may be scaled down by powers of two from a baseline cyclic prefix
duration of 4.7 µs, for example, for a numerology in an NR configuration or any other
radio configurations. Numerologies may be defined with the following subcarrier spacing/cyclic
prefix duration combinations: 15 kHz/4.7 µs; 30 kHz/2.3 µs; 60 kHz/1.2 µs; 120 kHz/0.59
µs; 240 kHz/0.29 µs, and/or any other subcarrier spacing/cyclic prefix duration combinations.
[0061] A slot may have a fixed number/quantity of OFDM symbols (e.g., 14 OFDM symbols).
A numerology with a higher subcarrier spacing may have a shorter slot duration and
more slots per subframe. Examples of numerologydependent slot duration and slots-per-subframe
transmission structure are shown in FIG. 7 (the numerology with a subcarrier spacing
of 240 kHz is not shown in FIG. 7). A subframe (e.g., in an NR configuration) may
be used as a numerology-independent time reference. A slot may be used as the unit
upon which uplink and downlink transmissions are scheduled. Scheduling (e.g., in an
NR configuration) may be decoupled from the slot duration. Scheduling may start at
any OFDM symbol. Scheduling may last for as many symbols as needed for a transmission,
for example, to support low latency. These partial slot transmissions may be referred
to as mini-slot or sub-slot transmissions.
[0062] FIG. 8 shows an example resource configuration of one or more carriers. The resource
configuration of may comprise a slot in the time and frequency domain for an NR carrier
or any other carrier. The slot may comprise resource elements (REs) and resource blocks
(RBs). A resource element (RE) may be the smallest physical resource (e.g., in an
NR configuration). An RE may span one OFDM symbol in the time domain by one subcarrier
in the frequency domain, such as shown in FIG. 8. An RB may span twelve consecutive
REs in the frequency domain, such as shown in FIG. 8. A carrier (e.g., an NR carrier)
may be limited to a width of a certain quantity of RBs and/or subcarriers (e.g., 275
RBs or 275×12 = 3300 subcarriers). Such limitation(s), if used, may limit the carrier
(e.g., NR carrier) frequency based on subcarrier spacing (e.g., carrier frequency
of 50, 100, 200, and 400 MHz for subcarrier spacings of 15,30, 60, and 120 kHz, respectively).
A 400 MHz bandwidth may be set based on a 400 MHz per carrier bandwidth limit. Any
other bandwidth may be set based on a per carrier bandwidth limit.
[0063] A single numerology may be used across the entire bandwidth of a carrier (e.g., an
NR such as shown in FIG. 8). In other example configurations, multiple numerologies
may be supported on the same carrier. NR and/or other access technologies may support
wide carrier bandwidths (e.g., up to 400 MHz for a subcarrier spacing of 120 kHz).
Not all wireless devices may be able to receive the full carrier bandwidth (e.g.,
due to hardware limitations and/or different wireless device capabilities). Receiving
and/or utilizing the full carrier bandwidth may be prohibitive, for example, in terms
of wireless device power consumption. A wireless device may adapt the size of the
receive bandwidth of the wireless device, for example, based on the amount of traffic
the wireless device is scheduled to receive (e.g., to reduce power consumption and/or
for other purposes). Such an adaptation may be referred to as bandwidth adaptation.
[0064] Configuration of one or more bandwidth parts (BWPs) may support one or more wireless
devices not capable of receiving the full carrier bandwidth. BWPs may support bandwidth
adaptation, for example, for such wireless devices not capable of receiving the full
carrier bandwidth. A BWP (e.g., a BWP of an NR configuration) may be defined by a
subset of contiguous RBs on a carrier. A wireless device may be configured (e.g.,
via an RRC layer) with one or more downlink BWPs per serving cell and one or more
uplink BWPs per serving cell (e.g., up to four downlink BWPs per serving cell and
up to four uplink BWPs per serving cell). One or more of the configured BWPs for a
serving cell may be active, for example, at a given time. The one or more BWPs may
be referred to as active BWPs of the serving cell. A serving cell may have one or
more first active BWPs in the uplink carrier and one or more second active BWPs in
the secondary uplink carrier, for example, if the serving cell is configured with
a secondary uplink carrier.
[0065] A downlink BWP from a set of configured downlink BWPs may be linked with an uplink
BWP from a set of configured uplink BWPs (e.g., for unpaired spectra). A downlink
BWP and an uplink BWP may be linked, for example, if a downlink BWP index of the downlink
BWP and an uplink BWP index of the uplink BWP are the same. A wireless device may
expect that the center frequency for a downlink BWP is the same as the center frequency
for an uplink BWP (e.g., for unpaired spectra).
[0066] A base station may configure a wireless device with one or more control resource
sets (CORESETs) for at least one search space. The base station may configure the
wireless device with one or more CORESETS, for example, for a downlink BWP in a set
of configured downlink BWPs on a primary cell (PCell) or on a secondary cell (SCell).
A search space may comprise a set of locations in the time and frequency domains where
the wireless device may monitor/find/detect/identify control information. The search
space may be a wireless device-specific search space (e.g., a UE-specific search space)
or a common search space (e.g., potentially usable by a plurality of wireless devices
or a group of wireless user devices). A base station may configure a group of wireless
devices with a common search space, on a PCell or on a primary secondary cell (PSCell),
in an active downlink BWP.
[0067] A base station may configure a wireless device with one or more resource sets for
one or more PUCCH transmissions, for example, for an uplink BWP in a set of configured
uplink BWPs. A wireless device may receive downlink receptions (e.g., PDCCH or PDSCH)
in a downlink BWP, for example, according to a configured numerology (e.g., a configured
subcarrier spacing and/or a configured cyclic prefix duration) for the downlink BWP.
The wireless device may send/transmit uplink transmissions (e.g., PUCCH or PUSCH)
in an uplink BWP, for example, according to a configured numerology (e.g., a configured
subcarrier spacing and/or a configured cyclic prefix length for the uplink BWP).
[0068] One or more BWP indicator fields may be provided/comprised in Downlink Control Information
(DCI). A value of a BWP indicator field may indicate which BWP in a set of configured
BWPs is an active downlink BWP for one or more downlink receptions. The value of the
one or more BWP indicator fields may indicate an active uplink BWP for one or more
uplink transmissions.
[0069] A base station may semi-statically configure a wireless device with a default downlink
BWP within a set of configured downlink BWPs associated with a PCell. A default downlink
BWP may be an initial active downlink BWP, for example, if the base station does not
provide/configure a default downlink BWP to/for the wireless device. The wireless
device may determine which BWP is the initial active downlink BWP, for example, based
on a CORESET configuration obtained using the PBCH.
[0070] A base station may configure a wireless device with a BWP inactivity timer value
for a PCell. The wireless device may start or restart a BWP inactivity timer at any
appropriate time. The wireless device may start or restart the BWP inactivity timer,
for example, if one or more conditions are satisfied. The one or more conditions may
comprise at least one of: the wireless device detects DCI indicating an active downlink
BWP other than a default downlink BWP for a paired spectra operation; the wireless
device detects DCI indicating an active downlink BWP other than a default downlink
BWP for an unpaired spectra operation; and/or the wireless device detects DCI indicating
an active uplink BWP other than a default uplink BWP for an unpaired spectra operation.
The wireless device may start/run the BWP inactivity timer toward expiration (e.g.,
increment from zero to the BWP inactivity timer value, or decrement from the BWP inactivity
timer value to zero), for example, if the wireless device does not detect DCI during
a time interval (e.g., 1 ms or 0.5 ms). The wireless device may switch from the active
downlink BWP to the default downlink BWP, for example, if the BWP inactivity timer
expires.
[0071] A base station may semi-statically configure a wireless device with one or more BWPs.
A wireless device may switch an active BWP from a first BWP to a second BWP, for example,
after (e.g., based on or in response to) receiving DCI indicating the second BWP as
an active BWP. A wireless device may switch an active BWP from a first BWP to a second
BWP, for example, after (e.g., based on or in response to) an expiry of the BWP inactivity
timer (e.g., if the second BWP is the default BWP).
[0072] A downlink BWP switching may refer to switching an active downlink BWP from a first
downlink BWP to a second downlink BWP (e.g., the second downlink BWP is activated
and the first downlink BWP is deactivated). An uplink BWP switching may refer to switching
an active uplink BWP from a first uplink BWP to a second uplink BWP (e.g., the second
uplink BWP is activated and the first uplink BWP is deactivated). Downlink and uplink
BWP switching may be performed independently (e.g., in paired spectrum/spectra). Downlink
and uplink BWP switching may be performed simultaneously (e.g., in unpaired spectrum/spectra).
Switching between configured BWPs may occur, for example, based on RRC signaling,
DCI signaling, expiration of a BWP inactivity timer, and/or an initiation of random
access.
[0073] FIG. 9 shows an example of configured BWPs. Bandwidth adaptation using multiple BWPs
(e.g., three configured BWPs for an NR carrier) may be available. A wireless device
configured with multiple BWPs (e.g., the three BWPs) may switch from one BWP to another
BWP at a switching point. The BWPs may comprise: a BWP 902 having a bandwidth of 40
MHz and a subcarrier spacing of 15 kHz; a BWP 904 having a bandwidth of 10 MHz and
a subcarrier spacing of 15 kHz; and a BWP 906 having a bandwidth of 20 MHz and a subcarrier
spacing of 60 kHz. The BWP 902 may be an initial active BWP, and the BWP 904 may be
a default BWP. The wireless device may switch between BWPs at switching points. The
wireless device may switch from the BWP 902 to the BWP 904 at a switching point 908.
The switching at the switching point 908 may occur for any suitable reasons. The switching
at a switching point 908 may occur, for example, after (e.g., based on or in response
to) an expiry of a BWP inactivity timer (e.g., indicating switching to the default
BWP). The switching at the switching point 908 may occur, for example, after (e.g.,
based on or in response to) receiving DCI indicating BWP 904 as the active BWP. The
wireless device may switch at a switching point 910 from an active BWP 904 to the
BWP 906, for example, after or in response receiving DCI indicating BWP 906 as a new
active BWP. The wireless device may switch at a switching point 912 from an active
BWP 906 to the BWP 904, for example, after (e.g., based on or in response to) an expiry
of a BWP inactivity timer. The wireless device may switch at the switching point 912
from an active BWP 906 to the BWP 904, for example, after or in response receiving
DCI indicating BWP 904 as a new active BWP. The wireless device may switch at a switching
point 914 from an active BWP 904 to the BWP 902, for example, after or in response
receiving DCI indicating the BWP 902 as a new active BWP.
[0074] Wireless device procedures for switching BWPs on a secondary cell may be the same/similar
as those on a primary cell, for example, if the wireless device is configured for
a secondary cell with a default downlink BWP in a set of configured downlink BWPs
and a timer value. The wireless device may use the timer value and the default downlink
BWP for the secondary cell in the same/similar manner as the wireless device uses
the timer value and/or default BWPs for a primary cell. The timer value (e.g., the
BWP inactivity timer) may be configured per cell (e.g., for one or more BWPs), for
example, via RRC signaling or any other signaling. One or more active BWPs may switch
to another BWP, for example, based on an expiration of the BWP inactivity timer.
[0075] Two or more carriers may be aggregated and data may be simultaneously sent/transmitted
to/from the same wireless device using carrier aggregation (CA) (e.g., to increase
data rates). The aggregated carriers in CA may be referred to as component carriers
(CCs). There may be a number/quantity of serving cells for the wireless device (e.g.,
one serving cell for a CC), for example, if CA is configured/used. The CCs may have
multiple configurations in the frequency domain.
[0076] FIG. 10A shows example CA configurations based on CCs. As shown in FIG. 10A, three
types of CA configurations may comprise an intraband (contiguous) configuration 1002,
an intraband (non-contiguous) configuration 1004, and/or an interband configuration
1006. In the intraband (contiguous) configuration 1002, two CCs may be aggregated
in the same frequency band (frequency band A) and may be located directly adjacent
to each other within the frequency band. In the intraband (non-contiguous) configuration
1004, two CCs may be aggregated in the same frequency band (frequency band A) but
may be separated from each other in the frequency band by a gap. In the interband
configuration 1006, two CCs may be located in different frequency bands (e.g., frequency
band A and frequency band B, respectively).
[0077] A network may set the maximum quantity of CCs that can be aggregated (e.g., up to
32 CCs may be aggregated in NR, or any other quantity may be aggregated in other systems).
The aggregated CCs may have the same or different bandwidths, subcarrier spacing,
and/or duplexing schemes (TDD, FDD, or any other duplexing schemes). A serving cell
for a wireless device using CA may have a downlink CC. One or more uplink CCs may
be optionally configured for a serving cell (e.g., for FDD). The ability to aggregate
more downlink carriers than uplink carriers may be useful, for example, if the wireless
device has more data traffic in the downlink than in the uplink.
[0078] One of the aggregated cells for a wireless device may be referred to as a primary
cell (PCell), for example, if a CA is configured. The PCell may be the serving cell
that the wireless initially connects to or access to, for example, during or at an
RRC connection establishment, an RRC connection reestablishment, and/or a handover.
The PCell may provide/configure the wireless device with NAS mobility information
and the security input. Wireless device may have different PCells. For the downlink,
the carrier corresponding to the PCell may be referred to as the downlink primary
CC (DL PCC). For the uplink, the carrier corresponding to the PCell may be referred
to as the uplink primary CC (UL PCC). The other aggregated cells (e.g., associated
with CCs other than the DL PCC and UL PCC) for the wireless device may be referred
to as secondary cells (SCells). The SCells may be configured, for example, after the
PCell is configured for the wireless device. An SCell may be configured via an RRC
connection reconfiguration procedure. For the downlink, the carrier corresponding
to an SCell may be referred to as a downlink secondary CC (DL SCC). For the uplink,
the carrier corresponding to the SCell may be referred to as the uplink secondary
CC (UL SCC).
[0079] Configured SCells for a wireless device may be activated or deactivated, for example,
based on traffic and channel conditions. Deactivation of an SCell may cause the wireless
device to stop PDCCH and PDSCH reception on the SCell and PUSCH, SRS, and CQI transmissions
on the SCell. Configured SCells may be activated or deactivated, for example, using
a MAC CE (e.g., the MAC CE described with respect to FIG. 4B). A MAC CE may use a
bitmap (e.g., one bit per SCell) to indicate which SCells (e.g., in a subset of configured
SCells) for the wireless device are activated or deactivated. Configured SCells may
be deactivated, for example, after (e.g., based on or in response to) an expiration
of an SCell deactivation timer (e.g., one SCell deactivation timer per SCell may be
configured).
[0080] DCI may comprise control information, such as scheduling assignments and scheduling
grants, for a cell. DCI may be sent/transmitted via the cell corresponding to the
scheduling assignments and/or scheduling grants, which may be referred to as a self-scheduling.
DCI comprising control information for a cell may be sent/transmitted via another
cell, which may be referred to as a cross-carrier scheduling. Uplink control information
(UCI) may comprise control information, such as HARQ acknowledgments and channel state
feedback (e.g., CQI, PMI, and/or RI) for aggregated cells. UCI may be sent/transmitted
via an uplink control channel (e.g., a PUCCH) of the PCell or a certain SCell (e.g.,
an SCell configured with PUCCH). For a larger number of aggregated downlink CCs, the
PUCCH of the PCell may become overloaded. Cells may be divided into multiple PUCCH
groups.
[0081] FIG. 10B shows example group of cells. Aggregated cells may be configured into one
or more PUCCH groups (e.g., as shown in FIG. 10B). One or more cell groups or one
or more uplink control channel groups (e.g., a PUCCH group 1010 and a PUCCH group
1050) may comprise one or more downlink CCs, respectively. The PUCCH group 1010 may
comprise one or more downlink CCs, for example, three downlink CCs: a PCell 1011 (e.g.,
a DL PCC), an SCell 1012 (e.g., a DL SCC), and an SCell 1013 (e.g., a DL SCC). The
PUCCH group 1050 may comprise one or more downlink CCs, for example, three downlink
CCs: a PUCCH SCell (or PSCell) 1051 (e.g., a DL SCC), an SCell 1052 (e.g., a DL SCC),
and an SCell 1053 (e.g., a DL SCC). One or more uplink CCs of the PUCCH group 1010
may be configured as a PCell 1021 (e.g., a UL PCC), an SCell 1022 (e.g., a UL SCC),
and an SCell 1023 (e.g., a UL SCC). One or more uplink CCs of the PUCCH group 1050
may be configured as a PUCCH SCell (or PSCell) 1061 (e.g., a UL SCC), an SCell 1062
(e.g., a UL SCC), and an SCell 1063 (e.g., a UL SCC). UCI related to the downlink
CCs of the PUCCH group 1010, shown as UCI 1031, UCI 1032, and UCI 1033, may be sent/transmitted
via the uplink of the PCell 1021 (e.g., via the PUCCH of the PCell 1021). UCI related
to the downlink CCs of the PUCCH group 1050, shown as UCI 1071, UCI 1072, and UCI
1073, may be sent/transmitted via the uplink of the PUCCH SCell (or PSCell) 1061 (e.g.,
via the PUCCH of the PUCCH SCell 1061). A single uplink PCell may be configured to
send/transmit UCI relating to the six downlink CCs, for example, if the aggregated
cells shown in FIG. 10B are not divided into the PUCCH group 1010 and the PUCCH group
1050. The PCell 1021 may become overloaded, for example, if the UCIs 1031, 1032, 1033,
1071, 1072, and 1073 are sent/transmitted via the PCell 1021. By dividing transmissions
of UCI between the PCell 1021 and the PUCCH SCell (or PSCell) 1061, overloading may
be prevented and/or reduced.
[0082] A PCell may comprise a downlink carrier (e.g., the PCell 1011) and an uplink carrier
(e.g., the PCell 1021). An SCell may comprise only a downlink carrier. A cell, comprising
a downlink carrier and optionally an uplink carrier, may be assigned with a physical
cell ID and a cell index. The physical cell ID or the cell index may indicate/identify
a downlink carrier and/or an uplink carrier of the cell, for example, depending on
the context in which the physical cell ID is used. A physical cell ID may be determined,
for example, using a synchronization signal (e.g., PSS and/or SSS) sent/transmitted
via a downlink component carrier. A cell index may be determined, for example, using
one or more RRC messages. A physical cell ID may be referred to as a carrier ID, and
a cell index may be referred to as a carrier index. A first physical cell ID for a
first downlink carrier may refer to the first physical cell ID for a cell comprising
the first downlink carrier. Substantially the same/similar concept may apply to, for
example, a carrier activation. Activation of a first carrier may refer to activation
of a cell comprising the first carrier.
[0083] A multi-carrier nature of a PHY layer may be exposed/indicated to a MAC layer (e.g.,
in a CA configuration). A HARQ entity may operate on a serving cell. A transport block
may be generated per assignment/grant per serving cell. A transport block and potential
HARQ retransmissions of the transport block may be mapped to a serving cell.
[0084] For the downlink, a base station may send/transmit (e.g., unicast, multicast, and/or
broadcast), to one or more wireless devices, one or more reference signals (RSs) (e.g.,
PSS, SSS, CSI-RS, DM-RS, and/or PT-RS). For the uplink, the one or more wireless devices
may send/transmit one or more RSs to the base station (e.g., DM-RS, PT-RS, and/or
SRS). The PSS and the SSS may be sent/transmitted by the base station and used by
the one or more wireless devices to synchronize the one or more wireless devices with
the base station. A synchronization signal (SS) / physical broadcast channel (PBCH)
block may comprise the PSS, the SSS, and the PBCH. The base station may periodically
send/transmit a burst of SS/PBCH blocks, which may be referred to as SSBs.
[0085] FIG. 11A shows an example mapping of one or more SS/PBCH blocks. A burst of SS/PBCH
blocks may comprise one or more SS/PBCH blocks (e.g., 4 SS/PBCH blocks, as shown in
FIG. 11A). Bursts may be sent/transmitted periodically (e.g., every 2 frames, 20 ms,
or any other durations). A burst may be restricted to a half-frame (e.g., a first
half-frame having a duration of 5 ms). Such parameters (e.g., the number of SS/PBCH
blocks per burst, periodicity of bursts, position of the burst within the frame) may
be configured, for example, based on at least one of: a carrier frequency of a cell
in which the SS/PBCH block is sent/transmitted; a numerology or subcarrier spacing
of the cell; a configuration by the network (e.g., using RRC signaling); and/or any
other suitable factor(s). A wireless device may assume a subcarrier spacing for the
SS/PBCH block based on the carrier frequency being monitored, for example, unless
the radio network configured the wireless device to assume a different subcarrier
spacing.
[0086] The SS/PBCH block may span one or more OFDM symbols in the time domain (e.g., 4 OFDM
symbols, as shown in FIG. 11A or any other quantity/number of symbols) and may span
one or more subcarriers in the frequency domain (e.g., 240 contiguous subcarriers
or any other quantity/number of subcarriers). The PSS, the SSS, and the PBCH may have
a common center frequency. The PSS may be sent/transmitted first and may span, for
example, 1 OFDM symbol and 127 subcarriers. The SSS may be sent/transmitted after
the PSS (e.g., two symbols later) and may span 1 OFDM symbol and 127 subcarriers.
The PBCH may be sent/transmitted after the PSS (e.g., across the next 3 OFDM symbols)
and may span 240 subcarriers (e.g., in the second and fourth OFDM symbols as shown
in FIG. 11A) and/or may span fewer than 240 subcarriers (e.g., in the third OFDM symbols
as shown in FIG. 11A).
[0087] The location of the SS/PBCH block in the time and frequency domains may not be known
to the wireless device (e.g., if the wireless device is searching for the cell). The
wireless device may monitor a carrier for the PSS, for example, to find and select
the cell. The wireless device may monitor a frequency location within the carrier.
The wireless device may search for the PSS at a different frequency location within
the carrier, for example, if the PSS is not found after a certain duration (e.g.,
20 ms). The wireless device may search for the PSS at a different frequency location
within the carrier, for example, as indicated by a synchronization raster. The wireless
device may determine the locations of the SSS and the PBCH, respectively, for example,
based on a known structure of the SS/PBCH block if the PSS is found at a location
in the time and frequency domains. The SS/PBCH block may be a cell-defining SS block
(CD-SSB). A primary cell may be associated with a CD-SSB. The CD-SSB may be located
on a synchronization raster. A cell selection/search and/or reselection may be based
on the CD-SSB.
[0088] The SS/PBCH block may be used by the wireless device to determine one or more parameters
of the cell. The wireless device may determine a physical cell identifier (PCI) of
the cell, for example, based on the sequences of the PSS and the SSS, respectively.
The wireless device may determine a location of a frame boundary of the cell, for
example, based on the location of the SS/PBCH block. The SS/PBCH block may indicate
that it has been sent/transmitted in accordance with a transmission pattern. An SS/PBCH
block in the transmission pattern may be a known distance from the frame boundary
(e.g., a predefined distance for a RAN configuration among one or more networks, one
or more base stations, and one or more wireless devices).
[0089] The PBCH may use a QPSK modulation and/or forward error correction (FEC). The FEC
may use polar coding. One or more symbols spanned by the PBCH may comprise/carry one
or more DM-RSs for demodulation of the PBCH. The PBCH may comprise an indication of
a current system frame number (SFN) of the cell and/or a SS/PBCH block timing index.
These parameters may facilitate time synchronization of the wireless device to the
base station. The PBCH may comprise a MIB used to send/transmit to the wireless device
one or more parameters. The MIB may be used by the wireless device to locate remaining
minimum system information (RMSI) associated with the cell. The RMSI may comprise
a System Information Block Type 1 (SIB1). The SIB1 may comprise information for the
wireless device to access the cell. The wireless device may use one or more parameters
of the MIB to monitor a PDCCH, which may be used to schedule a PDSCH. The PDSCH may
comprise the SIB1. The SIB1 may be decoded using parameters provided/comprised in
the MIB. The PBCH may indicate an absence of SIB 1. The wireless device may be pointed
to a frequency, for example, based on the PBCH indicating the absence of SIB1. The
wireless device may search for an SS/PBCH block at the frequency to which the wireless
device is pointed.
[0090] The wireless device may assume that one or more SS/PBCH blocks sent/transmitted with
a same SS/PBCH block index are quasi co-located (QCLed) (e.g., having substantially
the same/similar Doppler spread, Doppler shift, average gain, average delay, and/or
spatial Rx parameters). The wireless device may not assume QCL for SS/PBCH block transmissions
having different SS/PBCH block indexes. SS/PBCH blocks (e.g., those within a half-frame)
may be sent/transmitted in spatial directions (e.g., using different beams that span
a coverage area of the cell). A first SS/PBCH block may be sent/transmitted in a first
spatial direction using a first beam, a second SS/PBCH block may be sent/transmitted
in a second spatial direction using a second beam, a third SS/PBCH block may be sent/transmitted
in a third spatial direction using a third beam, a fourth SS/PBCH block may be sent/transmitted
in a fourth spatial direction using a fourth beam, etc.
[0091] A base station may send/transmit a plurality of SS/PBCH blocks, for example, within
a frequency span of a carrier. A first PCI of a first SS/PBCH block of the plurality
of SS/PBCH blocks may be different from a second PCI of a second SS/PBCH block of
the plurality of SS/PBCH blocks. The PCIs of SS/PBCH blocks sent/transmitted in different
frequency locations may be different or substantially the same.
[0092] The CSI-RS may be sent/transmitted by the base station and used by the wireless device
to acquire/obtain/determine channel state information (CSI). The base station may
configure the wireless device with one or more CSI-RSs for channel estimation or any
other suitable purpose. The base station may configure a wireless device with one
or more of the same/similar CSI-RSs. The wireless device may measure the one or more
CSI-RSs. The wireless device may estimate a downlink channel state and/or generate
a CSI report, for example, based on the measuring of the one or more downlink CSI-RSs.
The wireless device may send/transmit the CSI report to the base station (e.g., based
on periodic CSI reporting, semi-persistent CSI reporting, and/or aperiodic CSI reporting).
The base station may use feedback provided by the wireless device (e.g., the estimated
downlink channel state) to perform a link adaptation.
[0093] The base station may semi-statically configure the wireless device with one or more
CSI-RS resource sets. A CSI-RS resource may be associated with a location in the time
and frequency domains and a periodicity. The base station may selectively activate
and/or deactivate a CSI-RS resource. The base station may indicate to the wireless
device that a CSI-RS resource in the CSI-RS resource set is activated and/or deactivated.
[0094] The base station may configure the wireless device to report CSI measurements. The
base station may configure the wireless device to provide CSI reports periodically,
aperiodically, or semi-persistently. For periodic CSI reporting, the wireless device
may be configured with a timing and/or periodicity of a plurality of CSI reports.
For aperiodic CSI reporting, the base station may request a CSI report. The base station
may command the wireless device to measure a configured CSI-RS resource and provide
a CSI report relating to the measurement(s). For semi-persistent CSI reporting, the
base station may configure the wireless device to send/transmit periodically, and
selectively activate or deactivate the periodic reporting (e.g., via one or more activation/deactivation
MAC CEs and/or one or more DCIs). The base station may configure the wireless device
with a CSI-RS resource set and CSI reports, for example, using RRC signaling.
[0095] The CSI-RS configuration may comprise one or more parameters indicating, for example,
up to 32 antenna ports (or any other quantity of antenna ports). The wireless device
may be configured to use/employ the same OFDM symbols for a downlink CSI-RS and a
CORESET, for example, if the downlink CSI-RS and CORESET are spatially QCLed and resource
elements associated with the downlink CSI-RS are outside of the physical resource
blocks (PRBs) configured for the CORESET. The wireless device may be configured to
use/employ the same OFDM symbols for a downlink CSI-RS and SS/PBCH blocks, for example,
if the downlink CSI-RS and SS/PBCH blocks are spatially QCLed and resource elements
associated with the downlink CSI-RS are outside of PRBs configured for the SS/PBCH
blocks.
[0096] Downlink DM-RSs may be sent/transmitted by a base station and received/used by a
wireless device for a channel estimation. The downlink DM-RSs may be used for coherent
demodulation of one or more downlink physical channels (e.g., PDSCH). A network (e.g.,
an NR network) may support one or more variable and/or configurable DM-RS patterns
for data demodulation. At least one downlink DM-RS configuration may support a front-loaded
DM-RS pattern. A front-loaded DM-RS may be mapped over one or more OFDM symbols (e.g.,
one or two adjacent OFDM symbols). A base station may semi-statically configure the
wireless device with a number/quantity (e.g. a maximum number/quantity) of front-loaded
DM-RS symbols for a PDSCH. A DM-RS configuration may support one or more DM-RS ports.
A DM-RS configuration may support up to eight orthogonal downlink DM-RS ports per
wireless device (e.g., for single user-MIMO). A DM-RS configuration may support up
to 4 orthogonal downlink DM-RS ports per wireless device (e.g., for multiuser-MIMO).
A radio network may support (e.g., at least for CP-OFDM) a common DM-RS structure
for downlink and uplink. A DM-RS location, a DM-RS pattern, and/or a scrambling sequence
may be the same or different. The base station may send/transmit a downlink DM-RS
and a corresponding PDSCH, for example, using the same precoding matrix. The wireless
device may use the one or more downlink DM-RSs for coherent demodulation/channel estimation
of the PDSCH.
[0097] A transmitter (e.g., a transmitter of a base station) may use a precoder matrices
for a part of a transmission bandwidth. The transmitter may use a first precoder matrix
for a first bandwidth and a second precoder matrix for a second bandwidth. The first
precoder matrix and the second precoder matrix may be different, for example, based
on the first bandwidth being different from the second bandwidth. The wireless device
may assume that a same precoding matrix is used across a set of PRBs. The set of PRBs
may be determined/indicated/identified/denoted as a precoding resource block group
(PRG).
[0098] A PDSCH may comprise one or more layers. The wireless device may assume that at least
one symbol with DM-RS is present on a layer of the one or more layers of the PDSCH.
A higher layer may configure one or more DMRSs for a PDSCH (e.g., up to 3 DMRSs for
the PDSCH). Downlink PT-RS may be sent/transmitted by a base station and used by a
wireless device, for example, for a phase-noise compensation. Whether a downlink PT-RS
is present or not may depend on an RRC configuration. The presence and/or the pattern
of the downlink PT-RS may be configured on a wireless device-specific basis, for example,
using a combination of RRC signaling and/or an association with one or more parameters
used/employed for other purposes (e.g., modulation and coding scheme (MCS)), which
may be indicated by DCI. A dynamic presence of a downlink PT-RS, if configured, may
be associated with one or more DCI parameters comprising at least MCS. A network (e.g.,
an NR network) may support a plurality of PT-RS densities defined in the time and/or
frequency domains. A frequency domain density (if configured/present) may be associated
with at least one configuration of a scheduled bandwidth. The wireless device may
assume a same precoding for a DM-RS port and a PT-RS port. The quantity/number of
PT-RS ports may be fewer than the quantity/number of DM-RS ports in a scheduled resource.
Downlink PT-RS may be configured/allocated/confined in the scheduled time/frequency
duration for the wireless device. Downlink PT-RS may be sent/transmitted via symbols,
for example, to facilitate a phase tracking at the receiver.
[0099] The wireless device may send/transmit an uplink DM-RS to a base station, for example,
for a channel estimation. The base station may use the uplink DM-RS for coherent demodulation
of one or more uplink physical channels. The wireless device may send/transmit an
uplink DM-RS with a PUSCH and/or a PUCCH. The uplink DM-RS may span a range of frequencies
that is similar to a range of frequencies associated with the corresponding physical
channel. The base station may configure the wireless device with one or more uplink
DM-RS configurations. At least one DM-RS configuration may support a front-loaded
DM-RS pattern. The front-loaded DM-RS may be mapped over one or more OFDM symbols
(e.g., one or two adjacent OFDM symbols). One or more uplink DMRSs may be configured
to send/transmit at one or more symbols of a PUSCH and/or a PUCCH. The base station
may semi-statically configure the wireless device with a number/quantity (e.g. the
maximum number/quantity) of front-loaded DM-RS symbols for the PUSCH and/or the PUCCH,
which the wireless device may use to schedule a single-symbol DM-RS and/or a double-symbol
DM-RS. A network (e.g., an NR network) may support (e.g., for cyclic prefix orthogonal
frequency division multiplexing (CP-OFDM)) a common DM-RS structure for downlink and
uplink. A DM-RS location, a DM-RS pattern, and/or a scrambling sequence for the DM-RS
may be substantially the same or different.
[0100] A PUSCH may comprise one or more layers. A wireless device may send/transmit at least
one symbol with DM-RS present on a layer of the one or more layers of the PUSCH. A
higher layer may configure one or more DMRSs (e.g., up to three DMRSs) for the PUSCH.
Uplink PT-RS (which may be used by a base station for a phase tracking and/or a phase-noise
compensation) may or may not be present, for example, depending on an RRC configuration
of the wireless device. The presence and/or the pattern of an uplink PT-RS may be
configured on a wireless device-specific basis (e.g., a UE-specific basis), for example,
by a combination of RRC signaling and/or one or more parameters configured/employed
for other purposes (e.g., MCS), which may be indicated by DCI. A dynamic presence
of an uplink PT-RS, if configured, may be associated with one or more DCI parameters
comprising at least MCS. A radio network may support a plurality of uplink PT-RS densities
defined in time/frequency domain. A frequency domain density (if configured/present)
may be associated with at least one configuration of a scheduled bandwidth. The wireless
device may assume a same precoding for a DM-RS port and a PT-RS port. A quantity/number
of PT-RS ports may be less than a quantity/number of DM-RS ports in a scheduled resource.
An uplink PT-RS may be configured/allocated/confined in the scheduled time/frequency
duration for the wireless device.
[0101] One or more SRSs may be sent/transmitted by a wireless device to a base station,
for example, for a channel state estimation to support uplink channel dependent scheduling
and/or a link adaptation. SRS sent/transmitted by the wireless device may enable/allow
a base station to estimate an uplink channel state at one or more frequencies. A scheduler
at the base station may use/employ the estimated uplink channel state to assign one
or more resource blocks for an uplink PUSCH transmission for the wireless device.
The base station may semi-statically configure the wireless device with one or more
SRS resource sets. For an SRS resource set, the base station may configure the wireless
device with one or more SRS resources. An SRS resource set applicability may be configured,
for example, by a higher layer (e.g., RRC) parameter. An SRS resource in a SRS resource
set of the one or more SRS resource sets (e.g., with the same/similar time domain
behavior, periodic, aperiodic, and/or the like) may be sent/transmitted at a time
instant (e.g., simultaneously), for example, if a higher layer parameter indicates
beam management. The wireless device may send/transmit one or more SRS resources in
SRS resource sets. A network (e.g., an NR network) may support aperiodic, periodic,
and/or semi-persistent SRS transmissions. The wireless device may send/transmit SRS
resources, for example, based on one or more trigger types. The one or more trigger
types may comprise higher layer signaling (e.g., RRC) and/or one or more DCI formats.
At least one DCI format may be used/employed for the wireless device to select at
least one of one or more configured SRS resource sets. An SRS trigger type 0 may refer
to an SRS triggered based on higher layer signaling. An SRS trigger type 1 may refer
to an SRS triggered based on one or more DCI formats. The wireless device may be configured
to send/transmit an SRS, for example, after a transmission of a PUSCH and a corresponding
uplink DM-RS if a PUSCH and an SRS are sent/transmitted in a same slot. A base station
may semi-statically configure a wireless device with one or more SRS configuration
parameters indicating at least one of following: a SRS resource configuration identifier;
a number of SRS ports; time domain behavior of an SRS resource configuration (e.g.,
an indication of periodic, semi-persistent, or aperiodic SRS); slot, mini-slot, and/or
subframe level periodicity; an offset for a periodic and/or an aperiodic SRS resource;
a number of OFDM symbols in an SRS resource; a starting OFDM symbol of an SRS resource;
an SRS bandwidth; a frequency hopping bandwidth; a cyclic shift; and/or an SRS sequence
ID.
[0102] An antenna port may be determined/defined such that the channel over which a symbol
on the antenna port is conveyed can be inferred from the channel over which another
symbol on the same antenna port is conveyed. The receiver may infer/determine the
channel (e.g., fading gain, multipath delay, and/or the like) for conveying a second
symbol on an antenna port, from the channel for conveying a first symbol on the antenna
port, for example, if the first symbol and the second symbol are sent/transmitted
on the same antenna port. A first antenna port and a second antenna port may be referred
to as quasi co-located (QCLed), for example, if one or more large-scale properties
of the channel over which a first symbol on the first antenna port is conveyed may
be inferred from the channel over which a second symbol on a second antenna port is
conveyed. The one or more large-scale properties may comprise at least one of: a delay
spread; a Doppler spread; a Doppler shift; an average gain; an average delay; and/or
spatial Receiving (Rx) parameters.
[0103] Channels that use beamforming may require beam management. Beam management may comprise
a beam measurement, a beam selection, and/or a beam indication. A beam may be associated
with one or more reference signals. A beam may be identified by one or more beamformed
reference signals. The wireless device may perform a downlink beam measurement, for
example, based on one or more downlink reference signals (e.g., a CSI-RS) and generate
a beam measurement report. The wireless device may perform the downlink beam measurement
procedure, for example, after an RRC connection is set up with a base station.
[0104] FIG. 11B shows an example mapping of one or more CSI-RSs. The CSI-RSs may be mapped
in the time and frequency domains. Each rectangular block shown in FIG. 11B may correspond
to a resource block (RB) within a bandwidth of a cell. A base station may send/transmit
one or more RRC messages comprising CSI-RS resource configuration parameters indicating
one or more CSI-RSs. One or more of parameters may be configured by higher layer signaling
(e.g., RRC and/or MAC signaling) for a CSI-RS resource configuration. The one or more
of the parameters may comprise at least one of : a CSI-RS resource configuration identity,
a number of CSI-RS ports, a CSI-RS configuration (e.g., symbol and resource element
(RE) locations in a subframe), a CSI-RS subframe configuration (e.g., a subframe location,
an offset, and periodicity in a radio frame), a CSI-RS power parameter, a CSI-RS sequence
parameter, a code division multiplexing (CDM) type parameter, a frequency density,
a transmission comb, quasi co-location (QCL) parameters (e.g., QCL-scramblingidentity,
crs-portscount, mbsfn-subframeconfiglist, csi-rs-configZPid, qcl-csi-rs-configNZPid),
and/or other radio resource parameters.
[0105] One or more beams may be configured for a wireless device in a wireless device-specific
configuration. Three beams are shown in FIG. 11B (beam #1, beam #2, and beam #3),
but more or fewer beams may be configured. Beam #1 may be allocated with CSI-RS 1101
that may be sent/transmitted in one or more subcarriers in an RB of a first symbol.
Beam #2 may be allocated with CSI-RS 1102 that may be sent/transmitted in one or more
subcarriers in an RB of a second symbol. Beam #3 may be allocated with CSI-RS 1103
that may be sent/transmitted in one or more subcarriers in an RB of a third symbol.
A base station may use other subcarriers in the same RB (e.g., those that are not
used to send/transmit CSI-RS 1101) to transmit another CSI-RS associated with a beam
for another wireless device, for example, by using frequency division multiplexing
(FDM). Beams used for a wireless device may be configured such that beams for the
wireless device use symbols different from symbols used by beams of other wireless
devices, for example, by using time domain multiplexing (TDM). A wireless device may
be served with beams in orthogonal symbols (e.g., no overlapping symbols), for example,
by using the TDM.
[0106] CSI-RSs (e.g., CSI-RSs 1101, 1102, 1103) may be sent/transmitted by the base station
and used by the wireless device for one or more measurements. The wireless device
may measure an RSRP of configured CSI-RS resources. The base station may configure
the wireless device with a reporting configuration, and the wireless device may report
the RSRP measurements to a network (e.g., via one or more base stations) based on
the reporting configuration. The base station may determine, based on the reported
measurement results, one or more transmission configuration indication (TCI) states
comprising a number of reference signals. The base station may indicate one or more
TCI states to the wireless device (e.g., via RRC signaling, a MAC CE, and/or DCI).
The wireless device may receive a downlink transmission with an Rx beam determined
based on the one or more TCI states. The wireless device may or may not have a capability
of beam correspondence. The wireless device may determine a spatial domain filter
of a transmit (Tx) beam, for example, based on a spatial domain filter of the corresponding
Rx beam, if the wireless device has the capability of beam correspondence. The wireless
device may perform an uplink beam selection procedure to determine the spatial domain
filter of the Tx beam, for example, if the wireless device does not have the capability
of beam correspondence. The wireless device may perform the uplink beam selection
procedure, for example, based on one or more sounding reference signal (SRS) resources
configured to the wireless device by the base station. The base station may select
and indicate uplink beams for the wireless device, for example, based on measurements
of the one or more SRS resources sent/transmitted by the wireless device.
[0107] A wireless device may determine/assess (e.g., measure) a channel quality of one or
more beam pair links, for example, in a beam management procedure. A beam pair link
may comprise a Tx beam of a base station and an Rx beam of the wireless device. The
Tx beam of the base station may send/transmit a downlink signal, and the Rx beam of
the wireless device may receive the downlink signal. The wireless device may send/transmit
a beam measurement report, for example, based on the assessment/determination. The
beam measurement report may indicate one or more beam pair quality parameters comprising
at least one of: one or more beam identifications (e.g., a beam index, a reference
signal index, or the like), an RSRP, a precoding matrix indicator (PMI), a channel
quality indicator (CQI), and/or a rank indicator (RI).
[0108] FIG. 12A shows examples of downlink beam management procedures. One or more downlink
beam management procedures (e.g., downlink beam management procedures P1, P2, and
P3) may be performed. Procedure PI may enable a measurement (e.g., a wireless device
measurement) on Tx beams of a TRP (or multiple TRPs) (e.g., to support a selection
of one or more base station Tx beams and/or wireless device Rx beams). The Tx beams
of a base station and the Rx beams of a wireless device are shown as ovals in the
top row of PI and bottom row of P1, respectively. Beamforming (e.g., at a TRP) may
comprise a Tx beam sweep for a set of beams (e.g., the beam sweeps shown, in the top
rows of PI and P2, as ovals rotated in a counter-clockwise direction indicated by
the dashed arrows). Beamforming (e.g., at a wireless device) may comprise an Rx beam
sweep for a set of beams (e.g., the beam sweeps shown, in the bottom rows of PI and
P3, as ovals rotated in a clockwise direction indicated by the dashed arrows). Procedure
P2 may be used to enable a measurement (e.g., a wireless device measurement) on Tx
beams of a TRP (shown, in the top row of P2, as ovals rotated in a counter-clockwise
direction indicated by the dashed arrow). The wireless device and/or the base station
may perform procedure P2, for example, using a smaller set of beams than the set of
beams used in procedure P1, or using narrower beams than the beams used in procedure
P1. Procedure P2 may be referred to as a beam refinement. The wireless device may
perform procedure P3 for an Rx beam determination, for example, by using the same
Tx beam(s) of the base station and sweeping Rx beam(s) of the wireless device.
[0109] FIG. 12B shows examples of uplink beam management procedures. One or more uplink
beam management procedures (e.g., uplink beam management procedures U1, U2, and U3)
may be performed. Procedure U1 may be used to enable a base station to perform a measurement
on Tx beams of a wireless device (e.g., to support a selection of one or more Tx beams
of the wireless device and/or Rx beams of the base station). The Tx beams of the wireless
device and the Rx beams of the base station are shown as ovals in the top row of U1
and bottom row of U1, respectively). Beamforming (e.g., at the wireless device) may
comprise one or more beam sweeps, for example, a Tx beam sweep from a set of beams
(shown, in the bottom rows of U1 and U3, as ovals rotated in a clockwise direction
indicated by the dashed arrows). Beamforming (e.g., at the base station) may comprise
one or more beam sweeps, for example, an Rx beam sweep from a set of beams (shown,
in the top rows of U1 and U2, as ovals rotated in a counter-clockwise direction indicated
by the dashed arrows). Procedure U2 may be used to enable the base station to adjust
its Rx beam, for example, if the UE uses a fixed Tx beam. The wireless device and/or
the base station may perform procedure U2, for example, using a smaller set of beams
than the set of beams used in procedure P1, or using narrower beams than the beams
used in procedure PI. Procedure U2 may be referred to as a beam refinement. The wireless
device may perform procedure U3 to adjust its Tx beam, for example, if the base station
uses a fixed Rx beam.
[0110] A wireless device may initiate/start/perform a beam failure recovery (BFR) procedure,
for example, based on detecting a beam failure. The wireless device may send/transmit
a BFR request (e.g., a preamble, UCI, an SR, a MAC CE, and/or the like), for example,
based on the initiating the BFR procedure. The wireless device may detect the beam
failure, for example, based on a determination that a quality of beam pair link(s)
of an associated control channel is unsatisfactory (e.g., having an error rate higher
than an error rate threshold, a received signal power lower than a received signal
power threshold, an expiration of a timer, and/or the like).
[0111] The wireless device may measure a quality of a beam pair link, for example, using
one or more reference signals (RSs) comprising one or more SS/PBCH blocks, one or
more CSI-RS resources, and/or one or more DM-RSs. A quality of the beam pair link
may be based on one or more of a block error rate (BLER), an RSRP value, a signal
to interference plus noise ratio (SINR) value, an RSRQ value, and/or a CSI value measured
on RS resources. The base station may indicate that an RS resource is QCLed with one
or more DM-RSs of a channel (e.g., a control channel, a shared data channel, and/or
the like). The RS resource and the one or more DM-RSs of the channel may be QCLed,
for example, if the channel characteristics (e.g., Doppler shift, Doppler spread,
an average delay, delay spread, a spatial Rx parameter, fading, and/or the like) from
a transmission via the RS resource to the wireless device are similar or the same
as the channel characteristics from a transmission via the channel to the wireless
device.
[0112] A network (e.g., an NR network comprising a gNB and/or an ng-eNB) and/or the wireless
device may initiate/start/perform a random access procedure. A wireless device in
an RRC idle (e.g., an RRC IDLE) state and/or an RRC inactive (e.g., an RRC_INACTIVE)
state may initiate/perform the random access procedure to request a connection setup
to a network. The wireless device may initiate/start/perform the random access procedure
from an RRC connected (e.g., an RRC_CONNECTED) state. The wireless device may initiate/start/perform
the random access procedure to request uplink resources (e.g., for uplink transmission
of an SR if there is no PUCCH resource available) and/or acquire/obtain/determine
an uplink timing (e.g., if an uplink synchronization status is non-synchronized).
The wireless device may initiate/start/perform the random access procedure to request
one or more system information blocks (SIBs) (e.g., other system information blocks,
such as SIB2, SIB3, and/or the like). The wireless device may initiate/start/perform
the random access procedure for a beam failure recovery request. A network may initiate/start/perform
a random access procedure, for example, for a handover and/or for establishing time
alignment for an SCell addition.
[0113] FIG. 13A shows an example four-step random access procedure. The four-step random
access procedure may comprise a four-step contention-based random access procedure.
A base station may send/transmit a configuration message 1310 to a wireless device,
for example, before initiating the random access procedure. The four-step random access
procedure may comprise transmissions of four messages comprising: a first message
(e.g., Msg 1 1311), a second message (e.g., Msg 2 1312), a third message (e.g., Msg
3 1313), and a fourth message (e.g., Msg 4 1314). The first message (e.g., Msg 1 1311)
may comprise a preamble (or a random access preamble). The first message (e.g., Msg
1 1311) may be referred to as a preamble. The second message (e.g., Msg 2 1312) may
comprise as a random access response (RAR). The second message (e.g., Msg 2 1312)
may be referred to as an RAR.
[0114] The configuration message 1310 may be sent/transmitted, for example, using one or
more RRC messages. The one or more RRC messages may indicate one or more random access
channel (RACH) parameters to the wireless device. The one or more RACH parameters
may comprise at least one of: general parameters for one or more random access procedures
(e.g., RACH-configGeneral); cell-specific parameters (e.g., RACH-ConfigCommon); and/or
dedicated parameters (e.g., RACH-configDedicated). The base station may send/transmit
(e.g., broadcast or multicast) the one or more RRC messages to one or more wireless
devices. The one or more RRC messages may be wireless device-specific. The one or
more RRC messages that are wireless device-specific may be, for example, dedicated
RRC messages sent/transmitted to a wireless device in an RRC connected (e.g., an RRC_CONNECTED)
state and/or in an RRC inactive (e.g., an RRC_INACTIVE) state. The wireless devices
may determine, based on the one or more RACH parameters, a time-frequency resource
and/or an uplink transmit power for transmission of the first message (e.g., Msg 1
1311) and/or the third message (e.g., Msg 3 1313). The wireless device may determine
a reception timing and a downlink channel for receiving the second message (e.g.,
Msg 2 1312) and the fourth message (e.g., Msg 4 1314), for example, based on the one
or more RACH parameters.
[0115] The one or more RACH parameters provided/configured/comprised in the configuration
message 1310 may indicate one or more Physical RACH (PRACH) occasions available for
transmission of the first message (e.g., Msg 1 1311). The one or more PRACH occasions
may be predefined (e.g., by a network comprising one or more base stations). The one
or more RACH parameters may indicate one or more available sets of one or more PRACH
occasions (e.g., prach-ConfigIndex). The one or more RACH parameters may indicate
an association between (a) one or more PRACH occasions and (b) one or more reference
signals. The one or more RACH parameters may indicate an association between (a) one
or more preambles and (b) one or more reference signals. The one or more reference
signals may be SS/PBCH blocks and/or CSI-RSs. The one or more RACH parameters may
indicate a quantity/number of SS/PBCH blocks mapped to a PRACH occasion and/or a quantity/number
of preambles mapped to a SS/PBCH blocks.
[0116] The one or more RACH parameters provided/configured/comprised in the configuration
message 1310 may be used to determine an uplink transmit power of first message (e.g.,
Msg 1 1311) and/or third message (e.g., Msg 3 1313). The one or more RACH parameters
may indicate a reference power for a preamble transmission (e.g., a received target
power and/or an initial power of the preamble transmission). There may be one or more
power offsets indicated by the one or more RACH parameters. The one or more RACH parameters
may indicate: a power ramping step; a power offset between SSB and CSI-RS; a power
offset between transmissions of the first message (e.g., Msg 1 1311) and the third
message (e.g., Msg 3 1313); and/or a power offset value between preamble groups. The
one or more RACH parameters may indicate one or more thresholds, for example, based
on which the wireless device may determine at least one reference signal (e.g., an
SSB and/or CSI-RS) and/or an uplink carrier (e.g., a normal uplink (NUL) carrier and/or
a supplemental uplink (SUL) carrier).
[0117] The first message (e.g., Msg 1 1311) may comprise one or more preamble transmissions
(e.g., a preamble transmission and one or more preamble retransmissions). An RRC message
may be used to configure one or more preamble groups (e.g., group A and/or group B).
A preamble group may comprise one or more preambles. The wireless device may determine
the preamble group, for example, based on a pathloss measurement and/or a size of
the third message (e.g., Msg 3 1313). The wireless device may measure an RSRP of one
or more reference signals (e.g., SSBs and/or CSI-RSs) and determine at least one reference
signal having an RSRP above an RSRP threshold (e.g., rsrp-ThresholdSSB and/or rsrp-ThresholdCSI-RS).
The wireless device may select at least one preamble associated with the one or more
reference signals and/or a selected preamble group, for example, if the association
between the one or more preambles and the at least one reference signal is configured
by an RRC message.
[0118] The wireless device may determine the preamble, for example, based on the one or
more RACH parameters provided/configured/comprised in the configuration message 1310.
The wireless device may determine the preamble, for example, based on a pathloss measurement,
an RSRP measurement, and/or a size of the third message (e.g., Msg 3 1313). The one
or more RACH parameters may indicate: a preamble format; a maximum quantity/number
of preamble transmissions; and/or one or more thresholds for determining one or more
preamble groups (e.g., group A and group B). A base station may use the one or more
RACH parameters to configure the wireless device with an association between one or
more preambles and one or more reference signals (e.g., SSBs and/or CSI-RSs). The
wireless device may determine the preamble to be comprised in first message (e.g.,
Msg 1 1311), for example, based on the association if the association is configured.
The first message (e.g., Msg 1 1311) may be sent/transmitted to the base station via
one or more PRACH occasions. The wireless device may use one or more reference signals
(e.g., SSBs and/or CSI-RSs) for selection of the preamble and for determining of the
PRACH occasion. One or more RACH parameters (e.g., ra-ssb-OccasionMskIndex and/or
ra-OccasionList) may indicate an association between the PRACH occasions and the one
or more reference signals.
[0119] The wireless device may perform a preamble retransmission, for example, if no response
is received after (e.g., based on or in response to) a preamble transmission (e.g.,
for a period of time, such as a monitoring window for monitoring an RAR). The wireless
device may increase an uplink transmit power for the preamble retransmission. The
wireless device may select an initial preamble transmit power, for example, based
on a pathloss measurement and/or a target received preamble power configured by the
network. The wireless device may determine to resend/retransmit a preamble and may
ramp up the uplink transmit power. The wireless device may receive one or more RACH
parameters (e.g., PREAMBLE_POWER_RAMPING_STEP) indicating a ramping step for the preamble
retransmission. The ramping step may be an amount of incremental increase in uplink
transmit power for a retransmission. The wireless device may ramp up the uplink transmit
power, for example, if the wireless device determines a reference signal (e.g., SSB
and/or CSI-RS) that is the same as a previous preamble transmission. The wireless
device may count the quantity/number of preamble transmissions and/or retransmissions,
for example, using a counter parameter (e.g., PREAMBLE _TRANSMISSION COUNTER). The
wireless device may determine that a random access procedure has been completed unsuccessfully,
for example, if the quantity/number of preamble transmissions exceeds a threshold
configured by the one or more RACH parameters (e.g., preambleTransMax) without receiving
a successful response (e.g., an RAR).
[0120] The second message (e.g., Msg 2 1312) (e.g., received by the wireless device) may
comprise an RAR. The second message (e.g., Msg 2 1312) may comprise multiple RARs
corresponding to multiple wireless devices. The second message (e.g., Msg 2 1312)
may be received, for example, after (e.g., based on or in response to) the sending/transmitting
of the first message (e.g., Msg 1 1311). The second message (e.g., Msg 2 1312) may
be scheduled on the DL-SCH and may be indicated by a PDCCH, for example, using a random
access radio network temporary identifier (RA RNTI). The second message (e.g., Msg
2 1312) may indicate that the first message (e.g., Msg 1 1311) was received by the
base station. The second message (e.g., Msg 2 1312) may comprise a timealignment command
that may be used by the wireless device to adjust the transmission timing of the wireless
device, a scheduling grant for transmission of the third message (e.g., Msg 3 1313),
and/or a Temporary Cell RNTI (TC-RNTI). The wireless device may determine/start a
time window (e.g., ra-ResponseWindow) to monitor a PDCCH for the second message (e.g.,
Msg 2 1312), for example, after sending/transmitting the first message (e.g., Msg
1 1311) (e.g., a preamble). The wireless device may determine the start time of the
time window, for example, based on a PRACH occasion that the wireless device uses
to send/transmit the first message (e.g., Msg 1 1311) (e.g., the preamble). The wireless
device may start the time window one or more symbols after the last symbol of the
first message (e.g., Msg 1 1311) comprising the preamble (e.g., the symbol in which
the first message (e.g., Msg 1 1311) comprising the preamble transmission was completed
or at a first PDCCH occasion from an end of a preamble transmission). The one or more
symbols may be determined based on a numerology. The PDCCH may be mapped in a common
search space (e.g., a Type 1-PDCCH common search space) configured by an RRC message.
The wireless device may identify/determine the RAR, for example, based on an RNTI.
Radio network temporary identifiers (RNTIs) may be used depending on one or more events
initiating/starting the random access procedure. The wireless device may use a RA-RNTI,
for example, for one or more communications associated with random access or any other
purpose. The RA-RNTI may be associated with PRACH occasions in which the wireless
device sends/transmits a preamble. The wireless device may determine the RA-RNTI,
for example, based on at least one of: an OFDM symbol index; a slot index; a frequency
domain index; and/or a UL carrier indicator of the PRACH occasions. An example RA-RNTI
may be determined as follows:

where s_id may be an index of a first OFDM symbol of the PRACH occasion (e.g., 0
≤ s_id < 14), t_id may be an index of a first slot of the PRACH occasion in a system
frame (e.g., 0 ≤ t_id < 80), f_id may be an index of the PRACH occasion in the frequency
domain (e.g., 0 ≤ f id < 8), and ul_carrier_id may be a UL carrier used for a preamble
transmission (e.g., 0 for an NUL carrier, and 1 for an SUL carrier).
[0121] The wireless device may send/transmit the third message (e.g., Msg 3 1313), for example,
after (e.g., based on or in response to) a successful reception of the second message
(e.g., Msg 2 1312) (e.g., using resources identified in the Msg 2 1312). The third
message (e.g., Msg 3 1313) may be used, for example, for contention resolution in
the contention-based random access procedure. A plurality of wireless devices may
send/transmit the same preamble to a base station, and the base station may send/transmit
an RAR that corresponds to a wireless device. Collisions may occur, for example, if
the plurality of wireless device interpret the RAR as corresponding to themselves.
Contention resolution (e.g., using the third message (e.g., Msg 3 1313) and the fourth
message (e.g., Msg 4 1314)) may be used to increase the likelihood that the wireless
device does not incorrectly use an identity of another the wireless device. The wireless
device may comprise a device identifier in the third message (e.g., Msg 3 1313) (e.g.,
a C-RNTI if assigned, a TC RNTI comprised in the second message (e.g., Msg 2 1312),
and/or any other suitable identifier), for example, to perform contention resolution.
[0122] The fourth message (e.g., Msg 4 1314) may be received, for example, after (e.g.,
based on or in response to) the sending/transmitting of the third message (e.g., Msg
3 1313). The base station may address the wireless on the PDCCH (e.g., the base station
may send the PDCCH to the wireless device) using a C-RNTI, for example, If the C-RNTI
was included in the third message (e.g., Msg 3 1313). The random access procedure
may be determined to be successfully completed, for example, if the unique C RNTI
of the wireless device is detected on the PDCCH (e.g., the PDCCH is scrambled by the
C-RNTI). fourth message (e.g., Msg 4 1314) may be received using a DL-SCH associated
with a TC RNTI, for example, if the TC RNTI is comprised in the third message (e.g.,
Msg 3 1313) (e.g., if the wireless device is in an RRC idle (e.g., an RRC IDLE) state
or not otherwise connected to the base station). The wireless device may determine
that the contention resolution is successful and/or the wireless device may determine
that the random access procedure is successfully completed, for example, if a MAC
PDU is successfully decoded and a MAC PDU comprises the wireless device contention
resolution identity MAC CE that matches or otherwise corresponds with the CCCH SDU
sent/transmitted in third message (e.g., Msg 3 1313).
[0123] The wireless device may be configured with an SUL carrier and/or an NUL carrier.
An initial access (e.g., random access) may be supported via an uplink carrier. A
base station may configure the wireless device with multiple RACH configurations (e.g.,
two separate RACH configurations comprising: one for an SUL carrier and the other
for an NUL carrier). For random access in a cell configured with an SUL carrier, the
network may indicate which carrier to use (NUL or SUL). The wireless device may determine
to use the SUL carrier, for example, if a measured quality of one or more reference
signals (e.g., one or more reference signals associated with the NUL carrier) is lower
than a broadcast threshold. Uplink transmissions of the random access procedure (e.g.,
the first message (e.g., Msg 1 1311) and/or the third message (e.g., Msg 3 1313))
may remain on, or may be performed via, the selected carrier. The wireless device
may switch an uplink carrier during the random access procedure (e.g., between the
Msg 1 1311 and the Msg 3 1313). The wireless device may determine and/or switch an
uplink carrier for the first message (e.g., Msg 1 1311) and/or the third message (e.g.,
Msg 3 1313), for example, based on a channel clear assessment (e.g., a listen-before-talk).
[0124] FIG. 13B shows a two-step random access procedure. The two-step random access procedure
may comprise a two-step contention-free random access procedure. Similar to the four-step
contention-based random access procedure, a base station may, prior to initiation
of the procedure, send/transmit a configuration message 1320 to the wireless device.
The configuration message 1320 may be analogous in some respects to the configuration
message 1310. The procedure shown in FIG. 13B may comprise transmissions of two messages:
a first message (e.g., Msg 1 1321) and a second message (e.g., Msg 2 1322). The first
message (e.g., Msg 1 1321) and the second message (e.g., Msg 2 1322) may be analogous
in some respects to the first message (e.g., Msg 1 1311) and a second message (e.g.,
Msg 2 1312), respectively. The two-step contention-free random access procedure may
not comprise messages analogous to the third message (e.g., Msg 3 1313) and/or the
fourth message (e.g., Msg 4 1314).
[0125] The two-step (e.g., contention-free) random access procedure may be configured/initiated
for a beam failure recovery, other SI request, an SCell addition, and/or a handover.
A base station may indicate, or assign to, the wireless device a preamble to be used
for the first message (e.g., Msg 1 1321). The wireless device may receive, from the
base station via a PDCCH and/or an RRC, an indication of the preamble (e.g., ra-PreambleIndex).
[0126] The wireless device may start a time window (e.g., ra-ResponseWindow) to monitor
a PDCCH for the RAR, for example, after (e.g., based on or in response to) sending/transmitting
the preamble. The base station may configure the wireless device with one or more
beam failure recovery parameters, such as a separate time window and/or a separate
PDCCH in a search space indicated by an RRC message (e.g., recoverySearchSpaceId).
The base station may configure the one or more beam failure recovery parameters, for
example, in association with a beam failure recovery request. The separate time window
for monitoring the PDCCH and/or an RAR may be configured to start after sending/transmitting
a beam failure recovery request (e.g., the window may start any quantity of symbols
and/or slots after transmitting the beam failure recovery request). The wireless device
may monitor for a PDCCH transmission addressed to a Cell RNTI (C-RNTI) on the search
space. During the two-step (e.g., contention-free) random access procedure, the wireless
device may determine that a random access procedure is successful, for example, after
(e.g., based on or in response to) transmitting first message (e.g., Msg 1 1321) and
receiving a corresponding second message (e.g., Msg 2 1322). The wireless device may
determine that a random access procedure has successfully been completed, for example,
if a PDCCH transmission is addressed to a corresponding C-RNTI. The wireless device
may determine that a random access procedure has successfully been completed, for
example, if the wireless device receives an RAR comprising a preamble identifier corresponding
to a preamble sent/transmitted by the wireless device and/or the RAR comprises a MAC
sub-PDU with the preamble identifier. The wireless device may determine the response
as an indication of an acknowledgement for an SI request.
[0127] FIG. 13C shows an example two-step random access procedure. Similar to the random
access procedures shown in FIGS. 13A and 13B, a base station may, prior to initiation
of the procedure, send/transmit a configuration message 1330 to the wireless device.
The configuration message 1330 may be analogous in some respects to the configuration
message 1310 and/or the configuration message 1320. The procedure shown in FIG. 13C
may comprise transmissions of multiple messages (e.g., two messages comprising: a
first message (e.g., Msg A 1331) and a second message (e.g., Msg B 1332)).
[0128] Msg A 1331 may be sent/transmitted in an uplink transmission by the wireless device.
Msg A 1331 may comprise one or more transmissions of a preamble 1341 and/or one or
more transmissions of a transport block 1342. The transport block 1342 may comprise
contents that are similar and/or equivalent to the contents of the third message (e.g.,
Msg 3 1313) (e.g., shown in FIG. 13A). The transport block 1342 may comprise UCI (e.g.,
an SR, a HARQ ACK/NACK, and/or the like). The wireless device may receive the second
message (e.g., Msg B 1332), for example, after (e.g., based on or in response to)
sending/transmitting the first message (e.g., Msg A 1331). The second message (e.g.,
Msg B 1332) may comprise contents that are similar and/or equivalent to the contents
of the second message (e.g., Msg 2 1312) (e.g., an RAR shown in FIGS. 13A), the contents
of the second message (e.g., Msg 2 1322) (e.g., an RAR shown in FIG. 13B) and/or the
fourth message (e.g., Msg 4 1314) (e.g., shown in FIG. 13A).
[0129] The wireless device may start/initiate the two-step random access procedure (e.g.,
the two-step random access procedure shown in FIG. 13C) for a licensed spectrum and/or
an unlicensed spectrum. The wireless device may determine, based on one or more factors,
whether to start/initiate the two-step random access procedure. The one or more factors
may comprise at least one of: a radio access technology in use (e.g., LTE, NR, and/or
the like); whether the wireless device has a valid TA or not; a cell size; the RRC
state of the wireless device; a type of spectrum (e.g., licensed vs. unlicensed);
and/or any other suitable factors.
[0130] The wireless device may determine, based on two-step RACH parameters comprised in
the configuration message 1330, a radio resource and/or an uplink transmit power for
the preamble 1341 and/or the transport block 1342 (e.g., comprised in the first message
(e.g., Msg A 1331)). The RACH parameters may indicate an MCS, a time-frequency resource,
and/or a power control for the preamble 1341 and/or the transport block 1342. A time-frequency
resource for transmission of the preamble 1341 (e.g., a PRACH) and a time-frequency
resource for transmission of the transport block 1342 (e.g., a PUSCH) may be multiplexed
using FDM, TDM, and/or CDM. The RACH parameters may enable the wireless device to
determine a reception timing and a downlink channel for monitoring for and/or receiving
second message (e.g., Msg B 1332).
[0131] The transport block 1342 may comprise data (e.g., delay-sensitive data), an identifier
of the wireless device, security information, and/or device information (e.g., an
International Mobile Subscriber Identity (IMSI)). The base station may send/transmit
the second message (e.g., Msg B 1332) as a response to the first message (e.g., Msg
A 1331). The second message (e.g., Msg B 1332) may comprise at least one of: a preamble
identifier; a timing advance command; a power control command; an uplink grant (e.g.,
a radio resource assignment and/or an MCS); a wireless device identifier (e.g., a
UE identifier for contention resolution); and/or an RNTI (e.g., a C-RNTI or a TC-RNTI).
The wireless device may determine that the two-step random access procedure is successfully
completed, for example, if a preamble identifier in the second message (e.g., Msg
B 1332) corresponds to, or is matched to, a preamble sent/transmitted by the wireless
device and/or the identifier of the wireless device in second message (e.g., Msg B
1332) corresponds to, or is matched to, the identifier of the wireless device in the
first message (e.g., Msg A 1331) (e.g., the transport block 1342).
[0132] A wireless device and a base station may exchange control signaling (e.g., control
information). The control signaling may be referred to as L1/L2 control signaling
and may originate from the PHY layer (e.g., layer 1) and/or the MAC layer (e.g., layer
2) of the wireless device or the base station. The control signaling may comprise
downlink control signaling sent/transmitted from the base station to the wireless
device and/or uplink control signaling sent/transmitted from the wireless device to
the base station.
[0133] The downlink control signaling may comprise at least one of: a downlink scheduling
assignment; an uplink scheduling grant indicating uplink radio resources and/or a
transport format; slot format information; a preemption indication; a power control
command; and/or any other suitable signaling. The wireless device may receive the
downlink control signaling in a payload sent/transmitted by the base station via a
PDCCH. The payload sent/transmitted via the PDCCH may be referred to as downlink control
information (DCI). The PDCCH may be a group common PDCCH (GC-PDCCH) that is common
to a group of wireless devices. The GC-PDCCH may be scrambled by a group common RNTI.
[0134] A base station may attach one or more cyclic redundancy check (CRC) parity bits to
DCI, for example, in order to facilitate detection of transmission errors. The base
station may scramble the CRC parity bits with an identifier of a wireless device (or
an identifier of a group of wireless devices), for example, if the DCI is intended
for the wireless device (or the group of the wireless devices). Scrambling the CRC
parity bits with the identifier may comprise Modulo-2 addition (or an exclusive-OR
operation) of the identifier value and the CRC parity bits. The identifier may comprise
a 16-bit value of an RNTI.
[0135] DCI messages may be used for different purposes. A purpose may be indicated by the
type of an RNTI used to scramble the CRC parity bits. DCI having CRC parity bits scrambled
with a paging RNTI (P-RNTI) may indicate paging information and/or a system information
change notification. The P-RNTI may be predefined as "FFFE" in hexadecimal. DCI having
CRC parity bits scrambled with a system information RNTI (SI-RNTI) may indicate a
broadcast transmission of the system information. The SI-RNTI may be predefined as
"FFFF" in hexadecimal. DCI having CRC parity bits scrambled with a random access RNTI
(RA-RNTI) may indicate a random access response (RAR). DCI having CRC parity bits
scrambled with a cell RNTI (C-RNTI) may indicate a dynamically scheduled unicast transmission
and/or a triggering of PDCCH-ordered random access. DCI having CRC parity bits scrambled
with a temporary cell RNTI (TC-RNTI) may indicate a contention resolution (e.g., a
Msg 3 analogous to the Msg 3 1313 shown in FIG. 13A). Other RNTIs configured for a
wireless device by abase station may comprise a Configured Scheduling RNTI (CS RNTI),
a Transmit Power Control-PUCCH RNTI (TPC PUCCH-RNTI), a Transmit Power Control-PUSCH
RNTI (TPC-PUSCH-RNTI), a Transmit Power Control-SRS RNTI (TPC-SRS-RNTI), an Interruption
RNTI (INT-RNTI), a Slot Format Indication RNTI (SFI-RNTI), a Semi-Persistent CSI RNTI
(SP-CSI-RNTI), a Modulation and Coding Scheme Cell RNTI (MCS-C RNTI), and/or the like.
[0136] A base station may send/transmit DCI messages with one or more DCI formats, for example,
depending on the purpose and/or content of the DCI messages. DCI format 0 0 may be
used for scheduling of a PUSCH in a cell. DCI format 0_0 may be a fallback DCI format
(e.g., with compact DCI payloads). DCI format 0_1 may be used for scheduling of a
PUSCH in a cell (e.g., with more DCI payloads than DCI format 0_0). DCI format 1_0
may be used for scheduling of a PDSCH in a cell. DCI format 1_0 may be a fallback
DCI format (e.g., with compact DCI payloads). DCI format 1_1 may be used for scheduling
of a PDSCH in a cell (e.g., with more DCI payloads than DCI format 1_0). DCI format
2_0 may be used for providing a slot format indication to a group of wireless devices.
DCI format 2_1 may be used for informing/notifying a group of wireless devices of
a physical resource block and/or an OFDM symbol where the group of wireless devices
may assume no transmission is intended to the group of wireless devices. DCI format
2_2 may be used for transmission of a transmit power control (TPC) command for PUCCH
or PUSCH. DCI format 2_3 may be used for transmission of a group of TPC commands for
SRS transmissions by one or more wireless devices. DCI format(s) for new functions
may be defined in future releases. DCI formats may have different DCI sizes, or may
share the same DCI size.
[0137] The base station may process the DCI with channel coding (e.g., polar coding), rate
matching, scrambling and/or QPSK modulation, for example, after scrambling the DCI
with an RNTI. A base station may map the coded and modulated DCI on resource elements
used and/or configured for a PDCCH. The base station may send/transmit the DCI via
a PDCCH occupying a number of contiguous control channel elements (CCEs), for example,
based on a payload size of the DCI and/or a coverage of the base station. The number
of the contiguous CCEs (referred to as aggregation level) may be 1, 2, 4, 8, 16, and/or
any other suitable number. A CCE may comprise a number (e.g., 6) of resource-element
groups (REGs). A REG may comprise a resource block in an OFDM symbol. The mapping
of the coded and modulated DCI on the resource elements may be based on mapping of
CCEs and REGs (e.g., CCE-to-REG mapping).
[0138] FIG. 14A shows an example of CORESET configurations. The CORESET configurations may
be for a bandwidth part or any other frequency bands. The base station may send/transmit
DCI via a PDCCH on one or more control resource sets (CORESETs). A CORESET may comprise
a time-frequency resource in which the wireless device attempts/tries to decode DCI
using one or more search spaces. The base station may configure a size and a location
of the CORESET in the time-frequency domain. A first CORESET 1401 and a second CORESET
1402 may occur or may be set/configured at the first symbol in a slot. The first CORESET
1401 may overlap with the second CORESET 1402 in the frequency domain. A third CORESET
1403 may occur or may be set/configured at a third symbol in the slot. A fourth CORESET
1404 may occur or may be set/configured at the seventh symbol in the slot. CORESETs
may have a different number of resource blocks in frequency domain.
[0139] FIG. 14B shows an example of a CCE-to-REG mapping. The CCE-to-REG mapping may be
performed for DCI transmission via a CORESET and PDCCH processing. The CCE-to-REG
mapping may be an interleaved mapping (e.g., for the purpose of providing frequency
diversity) or a non-interleaved mapping (e.g., for the purposes of facilitating interference
coordination and/or frequency-selective transmission of control channels). The base
station may perform different or same CCE-to-REG mapping on different CORESETs. A
CORESET may be associated with a CCE-to-REG mapping (e.g., by an RRC configuration).
A CORESET may be configured with an antenna port QCL parameter. The antenna port QCL
parameter may indicate QCL information of a DM-RS for a PDCCH reception via the CORESET.
[0140] The base station may send/transmit, to the wireless device, one or more RRC messages
comprising configuration parameters of one or more CORESETs and one or more search
space sets. The configuration parameters may indicate an association between a search
space set and a CORESET. A search space set may comprise a set of PDCCH candidates
formed by CCEs (e.g., at a given aggregation level). The configuration parameters
may indicate at least one of: a number of PDCCH candidates to be monitored per aggregation
level; a PDCCH monitoring periodicity and a PDCCH monitoring pattern; one or more
DCI formats to be monitored by the wireless device; and/or whether a search space
set is a common search space set or a wireless device-specific search space set (e.g.,
a UE-specific search space set). A set of CCEs in the common search space set may
be predefined and known to the wireless device. A set of CCEs in the wireless device-specific
search space set (e.g., the UE-specific search space set) may be configured, for example,
based on the identity of the wireless device (e.g., C-RNTI).
[0141] As shown in FIG. 14B, the wireless device may determine a time-frequency resource
for a CORESET based on one or more RRC messages. The wireless device may determine
a CCE-to-REG mapping (e.g., interleaved or non-interleaved, and/or mapping parameters)
for the CORESET, for example, based on configuration parameters of the CORESET. The
wireless device may determine a number (e.g., at most 10) of search space sets configured
on/for the CORESET, for example, based on the one or more RRC messages. The wireless
device may monitor a set of PDCCH candidates according to configuration parameters
of a search space set. The wireless device may monitor a set of PDCCH candidates in
one or more CORESETs for detecting one or more DCI messages. Monitoring may comprise
decoding one or more PDCCH candidates of the set of the PDCCH candidates according
to the monitored DCI formats. Monitoring may comprise decoding DCI content of one
or more PDCCH candidates with possible (or configured) PDCCH locations, possible (or
configured) PDCCH formats (e.g., the number of CCEs, the number of PDCCH candidates
in common search spaces, and/or the number of PDCCH candidates in the wireless device-specific
search spaces) and possible (or configured) DCI formats. The decoding may be referred
to as blind decoding. The wireless device may determine DCI as valid for the wireless
device, for example, after (e.g., based on or in response to) CRC checking (e.g.,
scrambled bits for CRC parity bits of the DCI matching an RNTI value). The wireless
device may process information comprised in the DCI (e.g., a scheduling assignment,
an uplink grant, power control, a slot format indication, a downlink preemption, and/or
the like).
[0142] The wireless device may send/transmit uplink control signaling (e.g., UCI) to a base
station. The uplink control signaling may comprise HARQ acknowledgements for received
DL-SCH transport blocks. The wireless device may send/transmit the HARQ acknowledgements,
for example, after (e.g., based on or in response to) receiving a DL-SCH transport
block. Uplink control signaling may comprise CSI indicating a channel quality of a
physical downlink channel. The wireless device may send/transmit the CSI to the base
station. The base station, based on the received CSI, may determine transmission format
parameters (e.g., comprising multi-antenna and beamforming schemes) for downlink transmission(s).
Uplink control signaling may comprise scheduling requests (SR). The wireless device
may send/transmit an SR indicating that uplink data is available for transmission
to the base station. The wireless device may send/transmit UCI (e.g., HARQ acknowledgements
(HARQ-ACK), CSI report, SR, and the like) via a PUCCH or a PUSCH. The wireless device
may send/transmit the uplink control signaling via a PUCCH using one of several PUCCH
formats.
[0143] There may be multiple PUCCH formats (e.g., five PUCCH formats). A wireless device
may determine a PUCCH format, for example, based on a size of UCI (e.g., a quantity/number
of uplink symbols of UCI transmission and a number of UCI bits). PUCCH format 0 may
have a length of one or two OFDM symbols and may comprise two or fewer bits. The wireless
device may send/transmit UCI via a PUCCH resource, for example, using PUCCH format
0 if the transmission is over/via one or two symbols and the quantity/number of HARQ-ACK
information bits with positive or negative SR (HARQ-ACK/SR bits) is one or two. PUCCH
format 1 may occupy a number of OFDM symbols (e.g., between four and fourteen OFDM
symbols) and may comprise two or fewer bits. The wireless device may use PUCCH format
1, for example, if the transmission is over/via four or more symbols and the number
of HARQ-ACK/SR bits is one or two. PUCCH format 2 may occupy one or two OFDM symbols
and may comprise more than two bits. The wireless device may use PUCCH format 2, for
example, if the transmission is over/via one or two symbols and the quantity/number
of UCI bits is two or more. PUCCH format 3 may occupy a number of OFDM symbols (e.g.,
between four and fourteen OFDM symbols) and may comprise more than two bits. The wireless
device may use PUCCH format 3, for example, if the transmission is four or more symbols,
the quantity/number of UCI bits is two or more, and the PUCCH resource does not comprise
an orthogonal cover code (OCC). PUCCH format 4 may occupy a number of OFDM symbols
(e.g., between four and fourteen OFDM symbols) and may comprise more than two bits.
The wireless device may use PUCCH format 4, for example, if the transmission is four
or more symbols, the quantity/number of UCI bits is two or more, and the PUCCH resource
comprises an OCC.
[0144] The base station may send/transmit configuration parameters to the wireless device
for a plurality of PUCCH resource sets, for example, using an RRC message. The plurality
of PUCCH resource sets (e.g., up to four sets in NR, or up to any other quantity of
sets in other systems) may be configured on an uplink BWP of a cell. A PUCCH resource
set may be configured with a PUCCH resource set index, a plurality of PUCCH resources
with a PUCCH resource being identified by a PUCCH resource identifier (e.g., pucch-Resourceid),
and/or a number (e.g. a maximum number) of UCI information bits the wireless device
may send/transmit using one of the plurality of PUCCH resources in the PUCCH resource
set. The wireless device may select one of the plurality of PUCCH resource sets, for
example, based on a total bit length of the UCI information bits (e.g., HARQ-ACK,
SR, and/or CSI) if configured with a plurality of PUCCH resource sets. The wireless
device may select a first PUCCH resource set having a PUCCH resource set index equal
to "0," for example, if the total bit length of UCI information bits is two or fewer.
The wireless device may select a second PUCCH resource set having a PUCCH resource
set index equal to "1," for example, if the total bit length of UCI information bits
is greater than two and less than or equal to a first configured value. The wireless
device may select a third PUCCH resource set having a PUCCH resource set index equal
to "2," for example, if the total bit length of UCI information bits is greater than
the first configured value and less than or equal to a second configured value. The
wireless device may select a fourth PUCCH resource set having a PUCCH resource set
index equal to "3," for example, if the total bit length of UCI information bits is
greater than the second configured value and less than or equal to a third value (e.g.,
1406, 1706, or any other quantity of bits).
[0145] The wireless device may determine a PUCCH resource from the PUCCH resource set for
UCI (HARQ-ACK, CSI, and/or SR) transmission, for example, after determining a PUCCH
resource set from a plurality of PUCCH resource sets. The wireless device may determine
the PUCCH resource, for example, based on a PUCCH resource indicator in DCI (e.g.,
with DCI format 10 or DCI for 1_1) received on/via a PDCCH. An n-bit (e.g., a three-bit)
PUCCH resource indicator in the DCI may indicate one of multiple (e.g., eight) PUCCH
resources in the PUCCH resource set. The wireless device may send/transmit the UCI
(HARQ-ACK, CSI and/or SR) using a PUCCH resource indicated by the PUCCH resource indicator
in the DCI, for example, based on the PUCCH resource indicator.
[0146] FIG. 15A shows example communications between a wireless device and a base station.
A wireless device 1502 and a base station 1504 may be part of a communication network,
such as the communication network 100 shown in FIG. 1A, the communication network

over the air interface 1506 may be referred to as the downlink. The communication
direction from the wireless device 1502 to the base station 1504 over the air interface
may be referred to as the uplink. Downlink transmissions may be separated from uplink
transmissions, for example, using various duplex schemes (e.g., FDD, TDD, and/or some
combination of the duplexing techniques).
[0148] For the downlink, data to be sent to the wireless device 1502 from the base station
1504 may be provided/transferred/sent to the processing system 1508 of the base station
1504. The data may be provided/transferred/sent to the processing system 1508 by,
for example, a core network. For the uplink, data to be sent to the base station 1504
from the wireless device 1502 may be provided/transferred/sent to the processing system
1518 of the wireless device 1502. The processing system 1508 and the processing system
1518 may implement layer 3 and layer 2 OSI functionality to process the data for transmission.

1504 may be provided/transferred/sent to a transmission processing system 1520 of
the wireless device 1502, for example, after being processed by the processing system
1518. The transmission processing system 1510 and the transmission processing system
1520 may implement layer 1 OSI functionality. Layer 1 may comprise a PHY layer, for
example, described with respect to FIG. 2A, FIG. 2B, FIG. 3, and FIG. 4A. For sending/transmission
processing, the PHY layer may perform, for example, forward error correction coding
of transport channels, interleaving, rate matching, mapping of transport channels
to physical channels, modulation of physical channel, multiple-input multiple-output
(MIMO) or multi-antenna processing, and/or the like.
[0150] A reception processing system 1512 of the base station 1504 may receive the uplink
transmission from the wireless device 1502. The reception processing system 1512 of
the base station 1504 may comprise one or more TRPs. A reception processing system
1522 of the wireless device 1502 may receive the downlink transmission from the base
station 1504. The reception processing system 1522 of the wireless device 1502 may
comprise one or more antenna panels. The reception processing system 1512 and the
reception processing system 1522 may implement layer 1 OSI functionality. Layer 1
may include a PHY layer, for example, described with respect to FIG. 2A, FIG. 2B,
FIG. 3, and FIG. 4A. For receive processing, the PHY layer may perform, for example,
error detection, forward error correction decoding, deinterleaving, demapping of transport
channels to physical channels, demodulation of physical channels, MIMO or multi-antenna
processing, and/or the like.
[0151] The base station 1504 may comprise multiple antennas (e.g., multiple antenna panels,
multiple TRPs, etc.). The wireless device 1502 may comprise multiple antennas (e.g.,
multiple antenna panels, etc.). The multiple antennas may be used to perform one or
more MIMO or multi-antenna techniques, such as spatial multiplexing (e.g., singleuser
MIMO or multi-user MIMO), transmit/receive diversity, and/or beamforming. The wireless
device 1502 and/or the base station 1504 may have a single antenna.
[0152] The processing system 1508 and the processing system 1518 may be associated with
a memory 1514 and a memory 1524, respectively. Memory 1514 and memory 1524 (e.g.,
one or more non-transitory computer readable mediums) may store computer program instructions
or code that may be executed by the processing system 1508 and/or the processing system
1518, respectively, to carry out one or more of the functionalities (e.g., one or
more functionalities described herein and other functionalities of general computers,
processors, memories, and/or other peripherals). The transmission processing system
1510 and/or the reception processing system 1512 may be coupled to the memory 1514
and/or another memory (e.g., one or more non-transitory computer readable mediums)
storing computer program instructions or code that may be executed to carry out one
or more of their respective functionalities. The transmission processing system 1520
and/or the reception processing system 1522 may be coupled to the memory 1524 and/or
another memory (e.g., one or more non-transitory computer readable mediums) storing
computer program instructions or code that may be executed to carry out one or more
of their respective functionalities.
[0153] The processing system 1508 and/or the processing system 1518 may comprise one or
more controllers and/or one or more processors. The one or more controllers and/or
one or more processors may comprise, for example, a general-purpose processor, a digital
signal processor (DSP), a microcontroller, an application specific integrated circuit
(ASIC), a field programmable gate array (FPGA) and/or other programmable logic device,
discrete gate and/or transistor logic, discrete hardware components, an on-board unit,
or any combination thereof. The processing system 1508 and/or the processing system
1518 may perform at least one of signal coding/processing, data processing, power
control, input/output processing, and/or any other functionality that may enable the
wireless device 1502 and/or the base station 1504 to operate in a wireless environment.
[0154] The processing system 1508 may be connected to one or more peripherals 1516. The
processing system 1518 may be connected to one or more peripherals 1526. The one or
more peripherals 1516 and the one or more peripherals 1526 may comprise software and/or

serial bus (USB) port, a hands-free headset, a frequency modulated (FM) radio unit,
a media player, an Internet browser, an electronic control unit (e.g., for a motor
vehicle), and/or one or more sensors (e.g., an accelerometer, a gyroscope, a temperature
sensor, a radar sensor, a lidar sensor, an ultrasonic sensor, a light sensor, a camera,
and/or the like). The processing system 1508 and/or the processing system 1518 may
receive input data (e.g., user input data) from, and/or provide output data (e.g.,
user output data) to, the one or more peripherals 1516 and/or the one or more peripherals
1526. The processing system 1518 in the wireless device 1502 may receive power from
a power source and/or may be configured to distribute the power to the other components

power, for example, a battery, a solar cell, a fuel cell, or any combination thereof.
The processing system 1508 may be connected to a Global Positioning System (GPS) chipset
1517. The processing system 1518 may be connected to a Global Positioning System (GPS)
chipset 1527. The GPS chipset 1517 and the GPS chipset 1527 may be configured to determine
and provide geographic location information of the wireless device 1502 and the base

[0155] FIG. 15B shows example elements of a computing device that may be used to implement
any of the various devices described herein, including, for example, the base station
160A, 160B, 162A, 162B, 220, and/or 1504, the wireless device 106, 156A, 156B, 210,
and/or 1502, or any other base station, wireless device, AMF, UPF, network device,
or computing device described herein. The computing device 1530 may include one or
more processors 1531, which may execute instructions stored in the random-access memory
(RAM) 1533, the removable media 1534 (such as a Universal Serial Bus (USB) drive,
compact disk (CD) or digital versatile disk (DVD), or floppy disk drive), or any other
desired storage medium. Instructions may also be stored in an attached (or internal)
hard drive 1535. The computing device 1530 may also include a security processor (not
shown), which may execute instructions of one or more computer programs to monitor
the processes executing on the processor 1531 and any process that requests access
to any hardware and/or software components of the computing device 1530 (e.g., ROM
1532, RAM 1533, the removable media 1534, the hard drive 1535, the device controller
1537, a network interface 1539, a GPS 1541, a Bluetooth interface 1542, a WiFi interface
1543, etc.). The computing device 1530 may include one or more output devices, such
as the display 1536 (e.g., a screen, a display device, a monitor, a television, etc.),
and may include one or more output device controllers 1537, such as a video processor.
There may also be one or more user input devices 1538, such as a remote control, keyboard,
mouse, touch screen, microphone, etc. The computing device 1530 may also include one
or more network interfaces, such as a network interface 1539, which may be a wired
interface, a wireless interface, or a combination of the two. The network interface
1539 may provide an interface for the computing device 1530 to communicate with a
network 1540 (e.g., a RAN, or any other network). The network interface 1539 may include
a modem (e.g., a cable modem), and the external network 1540 may include communication
links, an external network, an inhome network, a provider's wireless, coaxial, fiber,
or hybrid fiber/coaxial distribution system (e.g., a DOCSIS network), or any other
desired network. Additionally, the computing device 1530 may include a location-detecting
device, such as a global positioning system (GPS) microprocessor 1541, which may be
configured to receive and process global positioning signals and determine, with possible
assistance from an external server and antenna, a geographic position of the computing
device 1530.
[0156] The example in FIG. 15B may be a hardware configuration, although the components
shown may be implemented as software as well. Modifications may be made to add, remove,
combine, divide, etc. components of the computing device 1530 as desired. Additionally,
the components may be implemented using basic computing devices and components, and
the same components (e.g., processor 1531, ROM storage 1532, display 1536, etc.) may
be used to implement any of the other computing devices and components described herein.
For example, the various components described herein may be implemented using computing
devices having components such as a processor executing computer-executable instructions
stored on a computer-readable medium, as shown in FIG. 15B. Some or all of the entities
described herein may be software based, and may co-exist in a common physical platform
(e.g., a requesting entity may be a separate software process and program from a dependent
entity, both of which may be executed as software on a common computing device).
[0157] FIG. 16A shows an example structure for uplink transmission. Processing of a baseband
signal representing a physical uplink shared channel may comprise/perform one or more
functions. The one or more functions may comprise at least one of: scrambling; modulation
of scrambled bits to generate complex-valued symbols; mapping of the complex-valued
modulation symbols onto one or several transmission layers; transform precoding to
generate complex-valued symbols; precoding of the complex-valued symbols; mapping
of precoded complex-valued symbols to resource elements; generation of complex-valued
time-domain Single Carrier-Frequency Division Multiple Access (SC-FDMA), CP-OFDM signal
for an antenna port, or any other signals; and/or the like. An SC-FDMA signal for
uplink transmission may be generated, for example, if transform precoding is enabled.
A CP-OFDM signal for uplink transmission may be generated, for example, if transform
precoding is not enabled (e.g., as shown in FIG. 16A). These functions are examples
and other mechanisms for uplink transmission may be implemented.
[0158] FIG. 16B shows an example structure for modulation and up-conversion of a baseband
signal to a carrier frequency. The baseband signal may be a complex-valued SC-FDMA,
CP-OFDM baseband signal (or any other baseband signals) for an antenna port and/or
a complex-valued Physical Random Access Channel (PRACH) baseband signal. Filtering
may be performed/employed, for example, prior to transmission.
[0159] FIG. 16C shows an example structure for downlink transmissions. Processing of a baseband
signal representing a physical downlink channel may comprise/perform one or more functions.
The one or more functions may comprise: scrambling of coded bits in a codeword to
be sent/transmitted on/via a physical channel; modulation of scrambled bits to generate
complex-valued modulation symbols; mapping of the complex-valued modulation symbols
onto one or several transmission layers; precoding of the complex-valued modulation
symbols on a layer for transmission on the antenna ports; mapping of complex-valued
modulation symbols for an antenna port to resource elements; generation of complex-valued
time-domain OFDM signal for an antenna port; and/or the like. These functions are
examples and other mechanisms for downlink transmission may be implemented.
[0160] FIG. 16D shows an example structure for modulation and up-conversion of a baseband
signal to a carrier frequency. The baseband signal may be a complex-valued OFDM baseband
signal for an antenna port or any other signal. Filtering may be performed/employed,
for example, prior to transmission.
[0161] A wireless device may receive, from a base station, one or more messages (e.g. RRC
messages) comprising configuration parameters of a plurality of cells (e.g., a primary
cell, one or more secondary cells). The wireless device may communicate with at least
one base station (e.g., two or more base stations in dual-connectivity) via the plurality
of cells. The one or more messages (e.g. as a part of the configuration parameters)
may comprise parameters of PHY, MAC, RLC, PCDP, SDAP, RRC layers for configuring the
wireless device. The configuration parameters may comprise parameters for configuring
PHY and MAC layer channels, bearers, etc. The configuration parameters may comprise
parameters indicating values of timers for PHY, MAC, RLC, PCDP, SDAP, RRC layers,
and/or communication channels.
[0162] A timer may begin running, for example, if it is started, and continue running until
it is stopped or until it expires. A timer may be started, for example, if it is not
running or restarted if it is running. A timer may be associated with a value (e.g.,
the timer may be started or restarted from a value or may be started from zero and
expire if it reaches the value). The duration of a timer may not be updated, for example,
until the timer is stopped or expires (e.g., due to BWP switching). A timer may be
used to measure a time period/window for a process. With respect to an implementation
and/or procedure related to one or more timers or other parameters, it will be understood
that there may be multiple ways to implement the one or more timers or other parameters.
One or more of the multiple ways to implement a timer may be used to measure a time
period/window for the procedure. A random access response window timer may be used
for measuring a window of time for receiving a random access response. The time difference
between two time stamps may be used, for example, instead of starting a random access
response window timer and determine the expiration of the timer. A process for measuring
a time window may be restarted, for example, if a timer is restarted. Other example
implementations may be configured/provided to restart a measurement of a time window.
[0163] FIG. 17A shows an example configuration of a wireless network. A wireless device
(e.g., wireless device 1704) may be in a range (or a coverage area) of a serving cell
(e.g., serving cell 1708). The serving cell may be associated with a corresponding
physical cell index (PCI). One or more other cells (e.g., non-serving cells, neighbor
cells, assisting cells, or candidate cells), such as a non-serving cell 1712, may
be installed/present within the range (or the coverage area) of the serving cell (e.g.,
serving cell 1708).
[0164] A distributed unit (DU) may serve the serving cell and the one or more cells. The
DU may support at least one of: an RLC layer, a MAC layer, and/or a PHY layer. The
DU may support lower layers (e.g., MAC layer, PHY layer, and/or the like) of a protocol
stack. The DU may comprise/include at least one of: a baseband processing functions
and/or RF functions. The DU may allocate a C-RNTI to the wireless device during a
random access procedure. The DU may support at least one of the following mobility
scenarios: intra-DU, intra-cell, inter-cell, inter-DU, inter-gNB, intra-gNB, and/or
inter-beam. An operation of the DU may be controlled by a centralized unit (CU).
[0165] The serving cell and the one or more cells may be connected to the (same) DU. Connection
of the serving cell and the one or more cells may be referred to as inter-cell multi-TRP
operation. The serving cell may be/comprise a first TRP. A second cell of the one
or more cells may be/comprise a second TRP. The serving cell may be associated with
the PCI. Each cell of the one or more cells may be associated with respective PCIs.
One or more of the respective PCIs may different from the PCI of the serving cell.
[0166] The one or more cells may comprise a non-serving cell (e.g., a second cell, non-serving
cell 1712, etc.). The second cell may be associated with a second PCI that is different
from the PCI of the serving cell. A coverage area of the serving cell (e.g., serving
cell 1708) may overlap with a coverage area of the second cell (e.g., non-serving
cell 1712). A network may install/comprise the one or more cells to boost the performance
of the serving cell. For example, the performance of the serving cell may be improved
via dynamic switching. Dynamic switching may comprise performing communications via
the second cell without performing a handover to the second cell. The wireless device
may receive (e.g., start receiving) downlink signals/transmissions (e.g., a PDCCH
transmission, a PDSCH transmission, DCI, CSI-RS, SS/PBCH blocks, and/or the like),
from a base station, via/from the second cell. The wireless device may receive the
downlink signals/transmissions without performing handover to the second cell, for
example, if the wireless device moves to a range/coverage area of the second cell.
The downlink signals/transmissions may be dedicated downlink signals/transmissions
(e.g., wireless device-specific scrambling C-RNTI). A downlink signal/transmission,
of the downlink signals/transmissions, may be quasi co-located with a reference signal
associated with the second cell. The wireless device (e.g., wireless device 1704)
may send/transmit (e.g., start sending/transmitting) one or more uplink signals/transmissions
(e.g., transport block, PUSCH, PUCCH, UCI, SRS) to the base station, via/to the second
cell (e.g., uplink signal 1720 which may be sent to the serving cell 1708 via a relay
transmission as shown in FIG. 17A), for example, if the wireless device moves to a
range (or a coverage area of) the second cell. The wireless device may send the one
or more uplink signals/transmissions via the second cell without performing handover
to the second cell (e.g., non-serving cell 1712). By not handing over to the second
cell (e.g., non-serving cell 1712), the wireless device may additionally or alternatively
send one or more uplink signals/transmissions (e.g., uplink signal 1716) via the serving
cell (e.g., serving cell 1708). The uplink signals/transmissions may be dedicated
uplink signals/transmissions (e.g., wireless device-specific scrambling C-RNTI). An
uplink signal/transmission of the uplink signals/transmissions may be quasi co-located
with a reference signal associated with the second cell.
[0167] A wireless device may receive, from a base station via a CORESET of a serving cell,
DCI. The DCI may schedule transmission of an uplink signal (e.g., PUSCH transmission,
data, transport block, PUCCH transmission, and the like). The uplink signal may be
an uplink signal 1716 as shown in FIG. 17A. Under at least some conditions, the wireless
device may determine a transmission power for the uplink signal based on a default
power control parameter (e.g., a default pathloss reference signal, a default target-received
power, a default pathloss compensation factor, and/or a default closed-loop index).
The wireless device may determine a transmission power for the uplink signal based
on a default power control parameter, for example, if the DCI doesn't comprise an
SRS resource indicator (SRI) field, if the DCI corresponds to a specific DCI format
(e.g., DCI format 0_0), and/or if a higher layer parameter (e.g., SRI-PUSCHPowerControl)
is not configured. The wireless device may send/transmit, via the serving cell, the
uplink transmission using the transmission power based on (e.g., indicated by) a default
power control parameter.
[0168] For example, the wireless device may determine a default pathloss reference signal
for transmission of the uplink signal. The default pathloss reference signal (RS)
may be indicated by/correspond to a pathloss reference RS with a pathloss reference
RS indicator/index (e.g., that is equal to zero, or any other value). The wireless
device may send/transmit the uplink signal with/using a transmission power that is
determined based on (e.g., indicated by) the default pathloss reference signal.
[0169] In an inter-cell multi-TRP operation, the wireless device may be (located) in a range
(or a coverage area) of a non-serving cell (e.g., a second cell, the non-serving cell
1712). For example, the wireless device may move into a coverage area of the non-serving
cell. The wireless device may send/transmit, to the base station via the second cell,
the uplink signal (e.g., the uplink signal 1720) based on a reference signal (e.g.,
SS/PBCH block, CSI-RS, SRS, and the like) of the non-serving cell. The wireless device
may send/transmit the uplink signal with a spatial domain transmission filter (or
a transmitting beam) determined based on the reference signal of the non-serving cell.
The wireless device may send/transmit the uplink signal with a transmission power
determined based on the reference signal of the non-serving cell.
[0170] For example, the wireless device may send/transmit the uplink signal (e.g., a PUSCH
transmission) via the non-serving cell (e.g., the second cell, using the spatial domain
transmission filter determined based on the reference signal of the second cell) even
if no handover has occurred from the serving cell. The wireless device may send/transmit
the uplink signal via the non-serving cell, for example, if the wireless device gets
closer to the non-serving cell. The non-serving cell may share (e.g., send, relay)
the received uplink signals with the serving cell via one or more backhaul links.
To be able to support the inter-cell multi-TRP operation as described above, a base
station may activate some one or more CORESETs of the serving cell with a transmission
configuration indication (TCI) state (or receiving beam) associated with a physical
cell index (PCI) of the serving cell and one or more CORESETs of the serving cell
with a TCI state associated with a PCI of the non-serving cell. The wireless device
may distinguish if a CORESET or any transport block scheduled via the CORESET belongs
to the serving cell or the non-serving cell, for example, based on a PCI corresponding
to a TCI state of the CORESET. The wireless device device may determine a spatial
domain transmission filter based on whether the CORESET, or any transport block scheduled
via the CORESET, belongs to the serving cell or the non-serving cell.
[0171] The wireless device may determine a default power control parameter during inter-cell
multi-TRP operation. The wireless device may determine a default power control parameter,
for example, if the wireless device receives DCI scheduling an uplink transmission
(e.g., PUSCH transmission, data, transport block, PUCCH transmission, and/or the like),
and if the conditions to determine a default power control parameter is satisfied
(e.g., the DCI doesn't comprise an SRI field, if the DCI corresponds to a specific
DCI format (e.g., DCI format 0_0), if a higher layer parameter (e.g., SRI-PUSCHPowerControl)
is not configured, and/or the like). Determining a transmission power computed based
on a default power control parameter may not be efficient, for example, if the wireless
device sends the uplink transmission via the non-serving cell (e.g., the uplink signal
1716). Using the same default power control parameter (e.g., the same default pathloss
reference signal) for transmissions via both the serving and non-serving cell may
not be efficient, for example, if the serving cell and the non-serving cell are not
co-located (e.g., TRPs of the serving cell and non-serving cell are not co-located).
The wireless device may be unable to determine an appropriate transmission power for
an uplink transmission via the non-serving cell, for example, if the default pathloss
reference signal (e.g., pathloss reference signal with index zero) belongs/corresponds
to the serving cell.
[0172] For example, a determined default pathloss reference signal may be associated with
(and/or configured for) the serving cell. Using the default pathloss reference signal
that may be associated with (and/or configured for) the serving cell may not be efficient,
for example, if the wireless device is (located) in the range (and/or the coverage
area) of the non-serving cell (and/or is transmitting via the non-serving cell). For
example, the serving cell and the non-serving cell may not be co-located and/or may
be subject to different channel conditions. Transmitting the uplink signal via the
non-serving cell using the transmission power that is determined based on the default
pathloss reference signal of (and/or configured for) the serving cell may result in
an inaccurate transmission power control. The inaccurate transmission power control
may increase interference to other cells and/or wireless devices. Increased interference
may reduce data rate and/or increase error rates.
[0173] Various examples herein may enhance transmission power control for various operation,
such as for inter-cell multi-TRP operation. A wireless device may receive DCI scheduling
an uplink transmission (e.g., a PUSCH transmission, a transport block, data, a PUCCH
transmission, and/or the like). The wireless device may determine whether the DCI
is associated with the serving cell or the second cell (e.g., non-serving cell). The
wireless device may determine a default power control parameter (e.g., a default pathloss
reference signal, a default target-received power, a default pathloss compensation
factor, and/or a default closed-loop index) associated with the serving cell, for
example, based on determining that the DCI is associated with the serving cell. The
wireless device may determine a transmission power for the uplink transmission based
on the default power control parameter associated with the serving cell, for example,
based on determining that the DCI is associated with the serving cell. The wireless
device may determine a default power control parameter associated with the second
cell, for example, based on determining that the DCI is associated with the second
cell. The wireless device may determine a transmission power based on the default
power control parameter associated with the second cell, for example, based on determining
that the DCI is associated with the second cell.
[0174] The wireless device may determine whether the DCI is associated with the serving
cell or the second cell based on a CORESET via which the DCI is received. The wireless
device may determine that the DCI is associated with the serving cell, for example,
if the wireless device receives the DCI via a CORESET that is associated with (or
a TCI state activated for the CORESET is associated with) a PCI of the serving cell.
The wireless device may determine that the DCI is associated with the non-serving
cell, for example, if the wireless device receives the DCI via a CORESET that is associated
with (or a TCI state activated for the CORESET is associated with) a PCI of the non-serving
cell.
[0175] A wireless device may receive, via a CORESET of a serving cell, DCI scheduling an
uplink transmission (e.g., PUSCH transmission). The wireless device may determine
a transmission power for the uplink transmission based on a first default power control
parameter, for example, if the CORESET (or a TCI state activated for the CORESET)
is associated with a PCI of the serving cell. The first default power control parameter
may comprise a first pathloss reference signal, a first target-received power, a first
pathloss compensation factor, and/or a first closed-loop index. The first pathloss
reference signal may have a lowest pathloss reference signal indicator/index among
pathloss reference signals associated with the PCI of the serving cell. The first
pathloss reference signal may have a pathloss reference signal index that is equal
to zero (or any other first value). Two sets of pathloss reference signals may be
configured, and the first pathloss reference signal may be a pathloss reference signal
with index zero (or any other value) in the first set of the two sets. The first closed-loop
index may be equal to zero (or any other third value).
[0176] The wireless device may determine a transmission power for the uplink transmission
based on a second default power control parameter, for example, if the CORESET (or
a TCI state activated for the CORESET) is associated with a PCI of the non-serving
cell. The second default power control parameter may comprise a second pathloss reference
signal, a second target-received power, a second pathloss compensation factor, and/or
a second closed-loop index. The second pathloss reference signal may have a lowest
pathloss reference signal indicator/index among pathloss reference signals associated
with the PCI of the non-serving cell. The second pathloss reference signal may have
a pathloss reference signal index that is equal to one (or any other second value
different from the first value). Two sets of pathloss reference signals may be configured,
and the second pathloss reference signal may be the pathloss reference signal with
index zero (or any other value) in the second set of the two sets. The second closed-loop
index may be equal to one (or any other fourth value different from the third value).
[0177] A wireless device may receive DCI scheduling an uplink transmission (e.g., a PUSCH
transmission, a transport block, data, a PUCCH transmission, and/or the like). The
wireless device may send the uplink transmissions based on a default power control
parameter. The default power control parameter (e.g., a default pathloss reference
signal) may be associated with a default PUCCH resource among a configured plurality
of PUCCH resources. The wireless device may determine, for transmission of the uplink
signal, the transmission power based on a pathloss reference signal indicated by the
default PUCCH resource.
[0178] Various examples as described herein may enable improved transmission power control,
increased data rate, reduced error rate, reduced retransmissions, and/or reduced power
consumption. Various examples as described herein may be applicable for determination
of default transmission/power control parameters (e.g., a default pathloss reference
signal, a default target received power, a default pathloss compensation factor, and/or
a default closed-loop process index).
[0179] A wireless device may determine/calculate/compute a transmission power (e.g., for
a PUSCH transmission). The wireless device may determine the transmission power in
a PUSCH transmission occasion i on an active uplink BWP
b of carrier
f of a serving cell c and with a PUSCH power control adjustment state with index
l, for example, based on the equation below:

[dBm], where
PCMAXf,c(

[0180] A value of an open-loop parameter may be equal to two (e.g., j = 2). The value of
the open-loop parameter being equal to two may indicate a scheduled PUSCH transmission
(e.g., via a dynamic uplink grant). A value of the open-loop parameter being equal
to zero (e.g., j = 0) may indicate a PUSCH transmission (e.g., Msg 3 transmission)
for a random access procedure. A value of the open-loop parameter being equal to one
(e.g., j = 1) may indicate a PUSCH transmission for a configured uplink grant (e.g.,
grant-free PUSCH transmission).
[0181] FIG. 17B shows an example default transmission parameter determination. The default
transmission parameter may correspond to a default power control parameter for determining
a transmission power of the uplink signal 1716. The wireless device 1708 may determine
the default power control parameter based on CORESET via which DCI scheduling the
uplink signal 1720 is received.

T0). The wireless device 1704 may receive the one or more messages from a base station.

cells.
[0183] The one or more cells may comprise a cell. The cell may be the serving cell 1708.
At least one configuration parameter of the one or more configuration parameters 1724
may be for a cell. The cell may be a primary cell (e.g., PCell), a secondary cell

GHz band, a 6 GHz band, etc.). The cell may be a licensed cell (e.g., operating in
a licensed band). The cell may operate in a first frequency range (e.g., FR1). FR1
may comprise frequency bands below 6 GHz (or any other first frequency bands). The
cell may operate in a second frequency range (e.g., FR2). FR2 may comprise frequency
bands from 24 GHz to 52.6 GHz (or any other second frequency bands). The cell may
operate in a third frequency range (e.g., FR3). FR3 may, comprise frequency bands
from 52.6 GHz to 71 GHz. The FR3 may comprise frequency bands starting from 52.6 GHz
(or any other third frequency bands).
[0184] The wireless device 1704 may perform uplink transmissions (e.g., a PUSCH transmission,
a PUCCH transmission, an SRS transmission) via the cell at a first time and via a
first frequency. The wireless device 1704 may perform downlink receptions (e.g., a
PDCCH reception, a PDSCH reception) via the cell at a second time and via a second
frequency. The cell may operate in a time-division duplex (TDD) mode. In the TDD mode,
the first frequency and the second frequency may be the same. In the TDD mode, the
first time and the second time may be different. The cell may operate in a frequency-division
duplex (FDD) mode. In the FDD mode, the first frequency and the second frequency may
be different. In the FDD mode, the first time and the second time may be the same.

block, CSI-RS) via a first CORESET with a first CORESET pool index (e.g., CoresetPoolIndex
= 0). A first CORESET pool may comprise the first CORESET. The first TRP may not send/transmit
a downlink signal/channel (e.g., PDSCH, PDCCH, DCI, SS/PBCH block, CSI-RS) via a second
CORESET with a second CORESET pool index (e.g., CoresetPoolIndex = 1) that is different
from the first CORESET pool index. A second CORESET pool, different from the first
CORESET pool, may comprise the second CORESET. The second TRP may send/transmit a

and the second CORESET. The one or more CORESET pool indexes may comprise the first
CORESET pool index and the second CORESET pool index.
[0201] A plurality of TRPs may serve (e.g., transmit to and/or receive from) the wireless
device 1704. The plurality of TRPs may comprise a first TRP and a second TRP. The
first TRP may send/transmit a downlink signal/channel (e.g., PDSCH, PDCCH, DCI, SS/PBCH

send/transmit a downlink signal/channel (e.g., PDSCH, PDCCH, DCI, SS/PBCH block, CSI-RS)
via a second CORESET in a second CORESET pool that is different from the first CORESET
pool. The second TRP may send/transmit a downlink signal/channel (e.g., PDSCH, PDCCH,
DCI, SS/PBCH block, CSI-RS) via a second CORESET in a second CORESET pool. The second
TRP may not send/transmit a downlink signal/channel (e.g., PDSCH, PDCCH, DCI, SS/PBCH

the second CORESET pool. The plurality of CORESETs may comprise the first CORESET
and the second CORESET.
[0202] The one or more configuration parameters 1724 may indicate at least two CORESET pool
indexes (e.g., 0 and 1) for a higher layer parameter (e.g., CORESETPoolIndex). The
one or more configuration parameters 1724 may comprise the higher layer parameter
CORESETPoolIndex with (or set to) the at least two CORESET pool indexes. The at least

CORESET pool index, for one or more second CORESETs of the plurality of CORESETs.
The one or more first CORESETs may comprise one or more third CORESETs, of the plurality
of CORESETs, without a value for a higher layer parameter CORESETPoolIndex. The one
or more configuration parameters may not comprise the higher layer parameter CORESETPoolIndex
for the one or more third CORESETs. The cell (e.g., the serving cell 1708) may be/comprise
the first TRP.
[0203] The one or more configuration parameters 1724 may indicate, for the cell, a physical
cell index/identity/identifier (PCI). The one or more configuration parameters 1724
may comprise a higher layer (or RRC) parameter (e.g., physCellId) indicating the PCI
for the cell. The PCI (e.g., PCI 1 as shown in FIG. 17) may identify a physical cell
identity of the cell.
[0204] The one or more configuration parameters 1724 may indicate, for a second cell, a
second PCI. The one or more configuration parameters 1724 may comprise a higher layer
(or RRC) parameter (e.g., physCellId) indicating the second PCI for the second cell.
The second PCI (e.g., PCI 2 as shown in FIG. 17) may identify a physical cell identity
of the second cell.
[0205] The second cell may be the non-serving cell 1712. The second cell may be a neighboring
cell. The second cell may be a candidate/assisting cell. The second cell may be/comprise
the second TRP.
[0206] The wireless device 1704 may receive a downlink signal. The downlink signal may be
quasi co-located with a reference signal of the second cell. The wireless device 1704
may receive the downlink signal via the cell. The downlink signal may be a downlink
reference signal (e.g., SS/PBCH block, CSI-RS, DMRS, and/or the like). The downlink
signal may be a PDSCH transmission (e.g., transport block, downlink data). The downlink
signal may be a PDCCH transmission (e.g., DCI 1728). The reference signal of the second
cell may be a SS/PBCH block.
[0207] The PCI of the cell and the second PCI of the second cell may be the same (e.g.,
intra-cell, intra-TRP operation/mode). The PCI of the cell and the second PCI of the
second cell may be different (e.g., inter-cell, inter-TRP operation/mode). A PCI indicated
by a higher layer (or RRC) parameter (e.g., physCellId) may be different from a cell
index/identity/identifier indicated by a higher layer (or RRC) parameter (e.g., servCellId

a wireless device (e.g., the wireless device 1704) receives DCI (e.g., the DCI 1728).
The CORESET pool index of the CORESET via/based on which the wireless device receives
DCI may be equal to a first value (e.g., 0, CoresetPoolIndex = 0, or any other value).
The (default) pathloss reference signal may be indicated by a pathloss reference RS
in the first list/set of pathloss reference RSs, for example, based on the CORESET
pool index of the CORESET being equal to the first value. The first list/set of pathloss
reference RSs may comprise the pathloss reference RS indicating the (default) pathloss
reference signal, for example, based on the CORESET pool index of the CORESET being
equal to the first value.
[0247] The CORESET that the wireless device receives the DCI may be associated with the
PCI of the cell (e.g., PCI 1 in FIG. 17B). The (default) pathloss reference signal
may be indicated by a pathloss reference RS in the first list/set of pathloss reference
RSs, for example, based on the CORESET being associated with the PCI of the cell.
The first list/set of pathloss reference RSs may comprise the pathloss reference RS
indicating the (default) pathloss reference signal, for example, based on the CORESET
being associated with the PCI of the cell.
[0248] The pathloss reference RS may be indicated/identified with a pathloss reference RS
index that is equal to zero (e.g., indicated by the higher layer parameter PUSCH-PathlossReferenceRS-Id
= 0), or any other value. The one or more first pathloss reference RS indexes may
comprise the pathloss reference RS index of the pathloss reference RS. For example,
in FIG. 18A, a pathloss reference RS index of the pathloss reference RS 0 in the first
set of pathloss reference RSs 1804 may be equal to zero. The (default) pathloss reference
signal may be SSB 1 indicated by the pathloss reference RS 0, for example, based on
the pathloss reference RS index of the pathloss reference RS 0 being equal to zero.
For example, in FIG. 18A, a pathloss reference RS index of the pathloss reference
RS 2 in the first set of pathloss reference RSs may be equal to zero. The (default)
pathloss reference signal may be SSB 2 indicated by the pathloss reference RS 2, for
example, based on the pathloss reference RS index of the pathloss reference RS 2 being
equal to zero.
[0249] The pathloss reference RS may be indicated/identified with a pathloss reference RS
index that is lowest/highest among the one or more first pathloss reference RS indexes
of the one or more first pathloss reference RSs. The one or more first pathloss reference
RS indexes may comprise the pathloss reference RS index of the pathloss reference
RS. For example, in FIG. 18A, a pathloss reference RS index of the pathloss reference
RS 0 may be lowest/highest among a pathloss reference RS index of the pathloss reference
RS 0, a pathloss reference RS index of the pathloss reference RS 1, a pathloss reference
RS index of the pathloss reference RS 2, and a pathloss reference RS index of the
pathloss reference RS 3. The (default) pathloss reference signal may be SSB 1 indicated
by the pathloss reference RS 0, for example, based on the pathloss reference RS index
of the pathloss reference RS 0 being lowest/highest among the pathloss reference RS
index of the pathloss reference RS 0, the pathloss reference RS index of the pathloss
reference RS 1, the pathloss reference RS index of the pathloss reference RS 2, and
the pathloss reference RS index of the pathloss reference RS 3. A pathloss reference
RS index of the pathloss reference RS 2 may be lowest/highest among a pathloss reference
RS index of the pathloss reference RS 0, a pathloss reference RS index of the pathloss
reference RS 1, a pathloss reference RS index of the pathloss reference RS 2, and
a pathloss reference RS index of the pathloss reference RS 3. The (default) pathloss
reference signal may be SSB 2 indicated by the pathloss reference RS 2, for example,
based on the pathloss reference RS index of the pathloss reference RS 2 being lowest/highest
among the pathloss reference RS index of the pathloss reference RS 0, the pathloss
reference RS index of the pathloss reference RS 1, the pathloss reference RS index
of the pathloss reference RS 2, and the pathloss reference RS index of the pathloss
reference RS 3.
[0250] The CORESET pool index of the CORESET via/based on which the wireless device receives
the DCI may be equal to a second value (e.g., 1, CoresetPoolIndex = 1, or any other
value). The (default) pathloss reference signal may be indicated by a pathloss reference
RS in the second list/set of pathloss reference RSs, for example, based on the CORESET
pool index of the CORESET being equal to the second value. The second list/set of
pathloss reference RSs may comprise the pathloss reference RS indicating the (default)
pathloss reference signal, for example, based on the CORESET pool index of the CORESET
being equal to the second value.
[0251] The CORESET via which the wireless device receives the DCI may be associated with
the second PCI of the second cell (e.g., PCI 2 in FIG. 17B). The (default) pathloss
reference signal may be indicated by a pathloss reference RS in the second list/set
of pathloss reference RSs, for example, based on the CORESET being associated with
the second PCI of the second cell. The second list/set of pathloss reference RSs may
comprise the pathloss reference RS indicating the default) pathloss reference signal,
for example, based on the CORESET being associated with the second PCI of the second
cell.
[0252] The pathloss reference RS may be indicated/identified with a pathloss reference RS
index that is equal to zero (e.g., indicated by the higher layer parameter PUSCH-PathlossReferenceRS-Id
= 0), or any other value. The one or more second pathloss reference RS indexes may
comprise the pathloss reference RS index of the pathloss reference RS. For example,
in FIG. 18A, a pathloss reference RS index of the pathloss reference RS 0 in the second
set of pathloss reference RSs 1808 may be equal to zero. The (default) pathloss reference
signal may be SSB 4 indicated by the pathloss reference RS 0, for example, based on
the pathloss reference RS index of the pPathloss reference RS 0 being equal to zero.
A pathloss reference RS index of the pathloss reference RS 1 in the second set of
pathloss reference RSs 1808 may be equal to zero. The (default) pathloss reference
signal may be CSI-RS 5 indicated by the pathloss reference RS 1, for example, based
on the pathloss reference RS index of the pathloss reference RS 1 being equal to zero.
[0253] The pathloss reference RS may be indicated/identified with a pathloss reference RS
index that is lowest/highest among the one or more second pathloss reference RS indexes
of the one or more second pathloss reference RSs. The one or more second pathloss
reference RS indexes may comprise the pathloss reference RS index of the pathloss
reference RS. For example, in FIG. 18A, a pathloss reference RS index of the pathloss
reference RS 0 may be lowest/highest among a pathloss reference RS index of the pathloss
reference RS 0, a pathloss reference RS index of the pathloss reference RS 1, and
a pathloss reference RS index of the pathloss reference RS 2. The (default) pathloss
reference signal may be SSB 4 indicated by the pathloss reference RS 0, for example,
based on the pathloss reference RS index of the pathloss reference RS 0 being lowest/highest
among the pathloss reference RS index of the pathloss reference RS 0, the pathloss
reference RS index of the pathloss reference RS 1, and the pathloss reference RS index
of the pathloss reference RS 2.
[0254] A pathloss reference RS index of the pathloss reference RS 1 may be lowest/highest
among a pathloss reference RS index of the pathloss reference RS 0, a pathloss reference
RS index of the pathloss reference RS 1, and a pathloss reference RS index of the
pathloss reference RS 2. The (default) pathloss reference signal may be CSI-RS 5 indicated
by the pathloss reference RS 1, for example, based on the pathloss reference RS index
of the pathloss reference RS 1 being lowest/highest among the pathloss reference RS
index of the pathloss reference RS 0, the pathloss reference RS index of the pathloss
reference RS 1, and the pathloss reference RS index of the pathloss reference RS 2.
[0255] The one or more configuration parameters may indicate/configure at least two sets/lists
of power control parameter sets. The at least two lists of power control parameter
sets may comprise a first list/set of power control parameter sets 1812 and a second

sri-PUSCH-MappingToAddModList2, and/or the like) indicating the second list of power
control parameter sets 1816.
[0256] The first list of power control parameter sets 1812 may comprise one or more first
power control parameter sets (e.g., indicated via higher layer parameter SRI-PUSCH-PowerControl).
The one or more first power control parameter sets may indicate (or be mapped to or

set of the one or more first power control parameter sets may indicate (or be mapped
to and/or be associated with) a respective pathloss reference RS of the one or more
first pathloss reference RSs. For example, a first power control parameter set of
the one or more first power control parameter sets may indicate (or be mapped to or
associated with) a first pathloss reference RS of the one or more first pathloss reference
RSs. A second power control parameter set of the one or more first power control parameter
sets may indicate (or be mapped to or associated with) a second pathloss reference
RS of the one or more first pathloss reference RSs. For example, as shown in FIG.
18B, the one or more first power control parameter sets may comprise/bee power control
parameter set 0, power control parameter set 1, power control parameter set 2, and
power control parameter set 3. The one or more first pathloss reference RSs may comprise/be

reference RSs may indicate/comprise (or be mapped to and/or be associated with) a
respective pathloss reference signal of the one or more first pathloss reference signals.
For example, the one or more first pathloss reference RSs indicated by (or mapped
to and/or associated with) the one or more first power control parameter sets may
be the one or more first pathloss reference RSs in FIG. 18A (e.g., in the first set
of pathloss reference RSs 1804).
[0257] The one or more configuration parameters may indicate, for the one or more first

power control parameter sets (e.g., indicated via higher layer parameter SRI-PUSCH-PowerControl).
The one or more second power control parameter sets may indicate (or be mapped to
and/or be associated with) one or more second pathloss reference RSs. Each power control
parameter set of the one or more second power control parameter sets may indicate
(or be mapped to and/or be associated with) a respective pathloss reference RS of
the one or more second pathloss reference RSs. For example, a first power control
parameter set of the one or more second power control parameter sets may indicate
(or be mapped to and/or be associated with) a first pathloss reference RS of the one
or more second pathloss reference RSs. A second power control parameter set of the
one or more second power control parameter sets may indicate (or be mapped to and/or

parameters may indicate, for each power control parameter set of the one or more second
power control parameter sets, a respective power control parameter set index of the
one or more second power control parameter set indexes. For example, the one or more
configuration parameters may indicate, for a first power control parameter set of
the one or more second power control parameter sets, a first power control parameter
set index of the one or more second power control parameter set indexes. The one or
more configuration parameters may indicate, for a second power control parameter set
of the one or more second power control parameter sets, a second power control parameter
set index of the one or more second power control parameter set indexes.
[0260] A single set/list of power control parameter sets may comprise the at least two sets/lists

parameter sets may comprise at least two subsets of power control parameter sets.
The one or more configuration parameters may indicate the single list of power control

The wireless device may distinguish/differentiate the first list of power control
parameter sets and the second list of power control parameter sets in the single list
of power control parameter sets, for example, based on a first indicator/index associated
with the first list of power control parameter sets and a second indicator/index associated
with the second list of power control parameter sets. The one or more configuration
parameters may indicate the first index (e.g., SRS resource set index, antenna panel

second PCI, and/or the like) for the one or more second power control parameter sets
in the second list of power control parameter sets. The one or more configuration
parameters may indicate the second index for each power control parameter set of the
one or more second power control parameter sets.
[0261] The (default) pathloss reference signal may be based on a CORESET and/or a CORESET
pool index of the CORESET via/based on which the wireless device (e.g., the wireless
device 1704) receives the DCI (e.g., the DCI 1728). The CORESET pool index of the
CORESET via/based on which the wireless device receives the DCI may be equal to a
first value (e.g., 0, indicated via a higher layer parameter CoresetPoolIndex = 0,
or any other value). The (default) pathloss reference signal may be indicated by a
pathloss reference RS indicated by (or mapped to and/or associated with) a power control
parameter set in the first list/set of power control parameter sets 1812, for example,
based on the CORESET pool index of the CORESET being equal to the first value. The

sri-PUSCH-PowerControlId = 0) or any other value. The one or more first power control

control parameter set. For example, in FIG. 18B, a power control parameter set index
of the power control parameter set 0 in the first list of power control parameter
sets 1812 may be equal to zero. The power control parameter set 0 may indicate (or
be mapped to and/or associated with) the pathloss reference RS 2. The (default) pathloss
reference signal may be SSB 2 indicated by the pathloss reference RS 2 that is mapped
to the power control parameter set 0, for example, based on the power control parameter
set index of the power control parameter set 0 being equal to zero. A power control

parameter set index that is lowest/highest among the one or more first power control
parameter set indexes of the one or more first power control parameter sets. The one
or more first power control parameter set indexes may comprise the power control parameter

parameter set index of the power control parameter set 0 may be lowest/highest among
a power control parameter set index of the power control parameter set 0, a power
control parameter set index of the power control parameter set 1, a power control
parameter set index of the power control parameter set 2, and a power control parameter
set index of the power control parameter set 3. The power control parameter set 0
may indicate (or be mapped to and/or associated with) the pathloss reference RS 2.
The (default) pathloss reference signal may be SSB 2 indicated by the pathloss reference

may be indicated by a pathloss reference RS indicated by (or mapped to and/or associated
with) a power control parameter set in the second list/set of power control parameter
sets 1816, for example, based on the CORESET pool index of the CORESET being equal

0 in the second list of power control parameter sets 1816 may be equal to zero. The
power control parameter set 0 may indicate (or be mapped to and/or be associated with)

0 being lowest/highest among the power control parameter set index of the power control
parameter set 0, the power control parameter set index of the power control parameter
set 1, and the power control parameter set index of the power control parameter set

[0269] For example, in FIG. 18B, a power control parameter set index of the power control
parameter set 2 may be lowest/highest among a power control parameter set index of
the power control parameter set 0, a power control parameter set index of the power
control parameter set 1, and a power control parameter set index of the power control

indicator/index of the one or more first target power level set indicators/indexes.
A first target power level set of the one or more first target power level sets may

For example, a first power control parameter set of the one or more first power control

one or more first target power level sets. The one or more configuration parameters
may indicate, for the first power control parameter set, a first target power level

1704) receives the DCI (e.g., the DCI 1728). The CORESET pool index of the CORESET
via/based on which the wireless device receives the DCI may be equal to a first value
(e.g., 0, indicated via a higher layer parameter CoresetPoolIndex = 0, or any other
value). The (default) target received power may be indicated by a target power-pathloss
